Old story (1980) but I don't remember hearing about it. I like numbers and such so I thought it interesting. Apparently a movie about it was also made - Lucky Numbers. https://thehustle.co/the-local-tv-star-who-rigged-the-lottery/
There is a newer story about the tech guy who figured out how to tap into the system with a little bit of work on his part. I think he found friends and relatives to play sets of numbers that would yield a winner and supposedly he actually didn't collect on the winnings, if I remember correctly just the people he told the numbers to play. Think he was doing it from an Iowa based lotto company.
Derren Brown predicted the numbers Live on TV in the UK, too late for anyone to use but he predicted then showed the broadcast live and got all of them right. Went through an entire show, showing how he predicted, then kinda admitted to fixing the machines, but not at the same time as that would be illegal and some how didn't get in any trouble for this stunt. Everyone believes he predicted with a group effort interesting, muppets!!
Randomization failure: the 1969 draft lottery http://faculty.rhodes.edu/wetzel/random/draftlottery.html During the early part of the Vietnam war, males could be exempt from serving in the military (and being sent to war) by attending college. Eventually this practice was ruled unfair (to people who couldn't afford college), so the college exemption was eliminated. In 1969 the Selective Service organized a lottery to decide which boys would be drafted into the military . They decided to draft people by randomly selecting people by their birthdates as follows: A piece of paper with each calendar day was put it in a capsule, and the capsule was dropped into a large bin set up like a hamster treadmill. The Head of the Selective Service stuck his hand into the bin and mixed things up for a few seconds, and then the bin was spun around for a few minutes. Blind-folded, the Selective Service Head reached in and pulled out a capsule--that date was assigned draft number #1, the next date was draft #2, until the last one was draft #366 (they included leap days). These numbers determined the order in which people would be drafted, and it was projected that about 10% of the males would be sent to Vietnam immediately after bootcamp and that another 10% would go to Vietnam within their period of enlistment. What do you see wrong with this procedure ? (type answer in the box) "So what WERE the problems?" The Challenge Some individuals (probably those with low numbers) noticed that those people with low numbers tended to be people born in the latter months of the year. In fact, the correlation between day of birth (1-366) and draft number was - .28. A random process would have produced a correlation around zero. Because this correlation was statistically significant, the lottery was challenged in court as being unfair. Do you think the lottery was unfair (to those born late in the year)? NO Yes The legal outcome Despite the statistical evidence and the plausible flaws you hopefully identified, the judge ruled the lottery to be fair and refused to have it redone. However, the military did correct these flaws in subsequent years. Addendum: the author of this exercise was drafted that year. Because he was born early in the year, he got a high number, thereby avoiding Vietnam and surviving long enough to write this exercise. So maybe you can blame the Selective Service for your having to do this web exercise!
