Approximating chaotic systemsReply
I don't know if this will help or not, but in both MM and PB they do two test draws that you don't get to see. So your numbers could have come up in the test draws. The winning numbers that come up are in past draws even the powerball or mega number. So pick 25-30 numbers and 5-10 bonus numbers from the past draws and pick from that pool of numbers and you have a better chance of winning, or you can just Quick Pick.

Math challenge - Mega Millions white ball range
There are 70 white (main) balls in Mega Millions. The player chooses 5 balls from 1 to 70 (or opts for a Quick Pick to randomly choose the same). Define R (for range) as max ball - min ball + 1 . For example, if the player chooses the balls {1, 2, 3, 4, 5}, then R = 5. Now consider the case where the balls are chosen randomly, such as a Quick Pick or lottery drawing for the winning numbers. R is now a random variable, and the set of all possible values of R is {1, 2, 3, ... , 70}. Suppose th

Is it true...Reply
I did some tests on that in which I picked a set of numbers and played it for every draw and along side of it, had the terminal do a different quick pick each time. Believe it or not, for Louisiana Lotto, Powerball, and MegaMillions, the random quick picks did better on matching numbers and getting winners than did the static set of numbers. None of them won jackpots and the prizes were all lower tier prizes, but the quick picks did do better at matching numbers statistically.

Chances of 1,2 or three winners in PowerballReply
The Lottos really should publish the repeat distribution, and number of plays per customer transaction, so that that P(x) could be better estimated. Also, their quick pick PRNG repeat distribution should be published. That would expose any problems with the PRNG and its seeding.

Expected Value of Lottery Jackpot, Given You Are A WinnerReply
This is an interesting topic, nice write up. In the past I have run simulations to find the probability distribution of the number of jackpot winners (under the assumption every ticket is a quick pick to simplify things) varying the parameters of total number of combinations and number of tickets sold. For example, in a 5/39 game, which is common in many states, there are 575757 combinations (a more manageable number). If 575757 quick picks are sold, the likelihoods of 0, 1, 2, 3, and 4+ jac

Mega Millions Just The JackpotReply
Interesting that the EVJ peaks. What assumptions did you make on repeat ticket picks? The PRNG (pseudo-random number generator) used in the Lotto ticket generating machines have not been been openly published, which is concerning. If those PRNGs are not seeded with enough bits of entropy (randomness), or the PRNG has a weakness, then the PRNG will not have a uniform pick probability, resulting in more repeats than expected from the quick picks.

Chances of 1,2 or three winners in PowerballReply
OK. My local TV news in TX says the cash value of the $1 Billion PowerBall Jackpot after income taxes is $325 million. (You would instantly become an evil 1%-er.) The probability of a single random ticket winning is 1 in 292201338. Nobody knows how many tickets will be bought before the fact, but 350M might be a reasonable (very rough) estimate based on history. If everybody bought a Quick Pick, the Expected Value of the cash after-tax Jackpot (per the Binomial Distribution) would be about $189

Math Geniuses, Help!! "SLAG" Odd/Even Analysis - Chart IReply
Guessing like an orangutan, or just doing a Quick Pick (same thing), is better than putting credence in some snip amamie lottery system claiming some meaning out of random fluctuations. Since you asked, what I would do (and, understand, lotteries are purely for entertainment) is create plays with completely random unique random numbers on each play. This can be easily done by someone with fairly basic programming skills. Why do this? Well, statistically, this has about the same Expected Value as

Math Geniuses, Help!! "SLAG" Odd/Even Analysis - Chart IReply
There is one way to optimize your play: select unique random numbers for each play in a given drawing, i.e. do not repeat numbers on successive lines. This is different than Quick-pick, which samples from a full set of balls on each line and therefore can have any number of repeats. Admittedly my approach will limit the number of plays, however. It will give an extremely slight improvement on the Expected Value of the return given the way pari-mutuel prize categories work. The main point, howeve
