it picks random numbers through a random sequence once i spin the reels and will determine which one of those symbols it wants to come up based on the probability we assign it. so...in this case, i was very close to getting 7-7-7, which would be a good combination and would have paid 120 coins. but unfortunately, the symbol next to the 7 was selected on the first and second reel, and i only got the 7 on the third reel. on any given game, i have no idea what's going to come up. its completely randomly determined each time. but over the long run, we know on average how often blank-blank-7 will come up based off the probability of blank on reel one, blank on reel two, and 7 on reel three. the longerhe player plays or the more they play on average, they probably will end up losing more. we're always looking for new, creative concepts and ways to create gambling events so that the player has the chance to win some real good money, have fun, and be entertained. >> dan, you found a galton box. >> i did find a galton box. and, the fact is, is that this is going to give us a very interesting

they are mapped out by hot spot and by random area. so what did we find? we found that from 2010 to 2011 we had 15.9 percent reduction in the number of locations where graffiti was found, an additional 14.4 percent this year in the number of locations. so what that's telling us is the graffiti tagging is becoming centralized into some of those locations. it's not the blanket approach. so it could affect and hopefully will inform us in terms of how our enforcement efforts are being done, as well as some of our clean up efforts if they are pushing into certain areas. so basically as far as the location where the graffiti is found, we've seen a 28 percent decrease. from 2010 to 2011 we had a huge drop in our graffiti, the amount of graffiti incidents that we were seeing, 42.7 percent reduction. what we did see this year was the amount of graffiti stagnated in terms of we may have had fewer locations of graffiti but we weren't seeing any less graffiti. so, again, the graffiti is becoming concentrated into those locations. it's important for us to be able to kn

in the random sample area the graffiti index averaged 8.2 compared to 8.39. again, they are fairly consist kupb stepblt from year to year. the hot spot increased in terms of its area. what we found again, 9 out of 20 neighborhoods had lowered graffiti indexes than last year, which makes sense we only had a 1.5 decrease in the amount of graffiti. it does tell us that the taggers are moving around from one neighborhood to the next, telling us how we should be managing or programs or which neighborhoods we should be looking at. this is a graphic analysis of the neighborhoods. i don't have a pointer, i'll get my head out of the way. downtown was one of our key problem areas that we started out with but we're seeing a steady decline in the downtown core. so basically we have been focusing a lot of our programming in the downtown area. we had a huge decrease in the gardineau neighborhood in the second year but something has happened in that neighborhood to pop it back up. so it's allowing us to look neighborhood by neighborhood to look at the community enforcement

the random area is showing more graffiti vandalism than the hot spot neighborhood, but the intensity is pretty clear. if we're going to tackle a neighborhood we need to be looking here, we need to be looking in here. so it's been very beneficial in terms of where we should be looking in terms of our programming. this is another example of another neighborhood where it was the complete opposite, it was very clear that the random area isn't as much of an issue as the hot spot area in that neighborhood and there's hardly any tagging done in the random area in 2012. so the larger dot means more intensity of graffiti. the highest rating that you can get for location intensity rating is 45. in the old strat conan rating the highest intensity we found was 35, so a fairly intense rating and the lowest was 12 in west mount and that fits with the trends of what's happening in those neighborhoods. so taggers is a very important part of the graffiti audit. when we first started the audit mark went on his observe and he was new to graffiti so him and his assistant did their best to log the tags.

. >> we do the random samples. but the department of health works with the police department and we create a random sample of approximately 450 stores to be visited every, it is about every 18 months and so we come up with kind of an annual, 18 month, and that is based on the random sample. which includes all supervisoral districts and all substation districts but it is randomized in such a way that it will go to 450 stores selected randomly. >> okay. >> it is consistent with how the state does a very similar, you know, inspection across california. is the san francisco enforcement, are the enforcement protocols similar? or taylored off of what the state does? >> they are virtually identical. the state also uses 15 and 16-year-olds and both insurance insure that young people have a valid id, for example. a lot of particularly in san francisco a lot of them don't drive and would not have a place to park a car or have the means to operate a car. so in many cases they would not have a valid california id and so the po

the randomized control trial is somewhat controversial for the reasons you say. actually can be done for a lot less. now can be done for a lot less than people attended the. and they would say for the gold level charities, the top of the two, the richest ones, the $3 billion red cross, you should be expecting gold level evidence of effectiveness. and part of that is not just because we should say it's gold level, a lot of things cherished you are really hard stuff. we know it's hard to educate kids. we've had sort of flatline educational system in this country for 50 years. we know it's hard to better health outcomes. a lot of ideas sound good, a lot of ideas are inspiring but actually don't move the needle. until we sort of take the hard drink and realize that things that sound that often don't actually help, and we really need to investigate and put the best resources into testing, whether it's randomized control on trials or not, i don't think we're going to get to where we need to be. so i start with the notion of let's rate -- raise the evidentiary baby cann

not random statistics. they even reward me for addressing my health risks.o i'm doing fine... but she's still going to give me a heart attack. we're more than 78,000 people looking out for more than 70 million americans. that's health in numbers. unitedhealthcare. >>> good morning. you are looking at a live shot of the white house. look how pretty. not snowing, not raining and spring is in the air. >> i love this music. >> get up and dance for us. >> i won't do that, but i love this music. jazzy, starting your day, 13 minutes after the hour. this will get you sitting up in bed, if not out of bed. >> hopefully. >> we heard some interesting things from lawmakers, interesting things that they probably should not have said. >> things that remember the declaration from louisiana governor, bobby jindal. >> we have to stop being the stupid party. it's time for a new republican party that talks like adults. there's no secret we had a number of republicans that damaged the image with bizarre comments. >> the message may have been missed. listen to this from the long

a moment ago, you walked through here, you have random faces of black people. if you to barack obama's faced in the test we see, i suspect the response of white people may be different, or does a better." which leads me to the question of whether or not some of this has to do with the right kind of black people that white folks respond to as opposed to just random black folks. does that make sense? >> yes, we can construct a random test, and this has been done, where we compare, we make the blackface is famous, admiral blackface is, and we make the white faces some of the better known mass murderers, and this produces a different result, not surprisingly, so it does make a difference. it is for that reason we do not use famous people's faces in this, but if you match the faces, using famous white and famous black, you will get the same. there is one on the web with cute little black and white children. tavis: even with babies. >> yes, and five-year-olds. it was very disturbing. this is not to say that people treat kids the way they treat adults or treat stars t

i think the notion that charities are going to be able to achieve randomized control trials across the board is never going to be scalable. it costs millions of dollars, tremendous research. also realities where a charity has to turn one person away and accept another person. a variety of challenges to doing that. do you see a way to get the results without requiring that standard for the charities? >> yeah. i think first of all, we saw the charities themselves having them articulate goals and deliver goals and then getting their -- asking them for the statistical approaches to measurement. i would -- the randomized control trial, which is somewhat controversy for the reasons you say, actually can be done for a lot less, now can be done for a lot less. for the gold level charities, the tom of the tier, the red crosss, we should be expecting gold level evidence of effectiveness. part of that is not just because we should -- it's because a lot of the things charities do are really hard stuff. we know it's actually hard to educate kids. we have had flatline educational system in this coun

. >> but what shook people is how random it was. and there's been a serious of crimes that were just random and evil. so, last year there was a woman walking down the street in middaylight stabbed by a man. recently there was a woman at a bus stop who somebody stole her stuff and shot her in the back of her head. so it's very arbitrary. people are looking for a pattern. you know, is it the homeless people? is it the drug problem? is it gangs? as paul, you know, went and looked into it, it's random evil. >> it is worth noting the city of santa cruz has a scholarship set up in honor of sergeant baker and detective butler and the information for donating to the scholarship is on the city's home page for people who want to continue to honor, i believe the effort raised $125,000. downtown businesses pledged from the very beginning. so another way to honor the memories of these two fallen officers. >>> some positive economic indicators to end the week. the dow jones industrial average keeps breaking records. it closed today at another all

they are mapped out by hot spot and by random area. so what did we find? we found that from 2010 to 2011 we had 15.9 percent reduction in the number of locations where graffiti was found, an additional 14.4 percent this year in the number of locations. so what that's telling us is the graffiti tagging is becoming centralized into some of those locations. it's not the blanket approach. so it could affect and hopefully will inform us in terms of how our enforcement efforts are being done, as well as some of our clean up efforts if they are pushing into certain areas. so basically as far as the location where the graffiti is found, we've seen a 28 percent decrease. from
