Chances of 1,2 or three winners in Powerball
I remembered somebody that would figure out the probability of one winner of two winners or multiple winners on Powerball and mega million when I got to a certain level just curious if anybody can share the link

My fascination -The first digitReply
This is high grade maths.....I'm pretty sure any good lottery player will grasp that Please try and understand whats a skip sequence -A skip sequence is 5 skips and it follows from the same skip 1 sequence -example skip 4 Hit on powerball on 19/ 7/23 and it hit again on 09 /08/ 23 4 42 11 3 3 3 -19 /7/23 Powerball 4 15 9 11 21 5 - 09/08/23 Powerball

My fascination -The first digitReply
Good point, Orange71. Let's see how impressive Ricklou's one-ball Powerball guesses are mathematically. Powerball is drawn approximately 156.5 times a year. If you guess one white ball out of 69, you have a 5/69 chance of getting it right. Over the course of a year of participating in all the one-ball Powerball challenges, a participant's expected number of correct guesses is approximately 156.5 * (5/69) 11.3 . One year he got it right 12 times, a difference of +0.7 over the expected va

Improved odds of a 5W Powerball win, or coincidence?
I've discovered a relationship in the Powerball draws which improves the odds of a 5 white ball hit by a factor of 35.7. 69 choose 5 = 11,238,513, so the odds of a 5W hit are 1 in 11,238,513, assuming the balls are equally likely to be picked. The relationship in past draws reduces the odds to 1 in 314,432 Still a long shot, but much improved. Standard statistical analysis will not sift out this 5W signal. I discovered it with exhaustive search. Could this relationship just b

Shuffling and Mixing
Lotto ball machines work well to randomize ball picks because of their mixing properties. A closely related problem is how many shuffles are sufficient to randomize a deck of cards. The following curve is pulled from an AMS (American Mathematic Society) post on this topic. A link to the post is given below. https://www.ams.org/publicoutreach/feature-column/fcarc-shuffle d is a measure of how close the pdf (probability distribution function) of the card ordering is from uni

Approximating chaotic systemsReply
Test results are posted on the powerball website. Click media center at bottom of page. Then draw results.

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.

Craps Pass Line SimulationReply
Thanks cottoneyedjoe. I may adapt this for a lotto game, like Powerball or Megamillions, just for the fun of it (and to see how much money a player is likely to lose over a lifetime, even with a modest weekly expenditure). If I do, I'll post it here. I'll also check out that crypto PRNG package.

Monty Hall Problem and Implications Explained
The Monty Hall problem is a famous case study in the application of Probability, specifically the concept of Conditional Probability. In simple terms Conditional Probability is the probability that something will occur given the additional information that something else has occurred. If something else is known to have occurred, it may or may not affect the probability of something . Examples of the probability of something not being affected by something else are (a) the outcome of the n-t
