Weird treesReply
Yes, definitely if it's a choice between operator error or an error in Wolfram Alpha, I'd go with operator error. That's how I got 30 first for red steady state trees with WolframAlpha.

Copy paste error on slide. Exceeded time limit to re-insert corrected image into post. Corrected equations (3) and (7) below. (Had wrong P subscripts.)

Chi-Squared Goodness of Fit Test for LotteriesReply
Yeah, the time variance of the statistics. They switch ball sets constantly, swap out individual balls when out of spec, etc. I have no model information for that time variance to incorporate into the estimation. Absent of a model, I account indirectly for time variant statistics with two time length parameters. During the discovery phase, which I'm still in, I adjust those parameters manually. Once I get a better feel of what information is available to help estimation, I can automate that para

Powerball Probability QuestionReply
This is good but there is an error in your calculation. The question was what is the probability two tickets win the same amount (not, match the same number of balls). 0/1 and 1/1 win the same amount -- $4 2/1 and 3/0 win the same amount -- $7 3/1 and 4/0 win the same amount -- $100 The calculation should be done with those three groups of two equal prizes added together. The probability of two Powerball tickets winning the same amount (given that both are winners) is very

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

Expected Value of Lottery Jackpot, Given You Are A Winner
When you play a lottery and win a pari-mutuel Jackpot, there's always the possibility that one or more other players will also have won, and you'll be sharing (splitting) the prize money. Can you calculate what the Expected Value is of the Jackpot prize, given you are a winner? Certainly! We need to assume something first: every ticket bought is a Quickpick - so any given set of numbers (a single ticket) can be randomly replicated on any other ticket. Suppose there are N such tickets sold (1
