Question 593686: In the FAQ section of the Wisconsin Lottery website is the question, "If the overall odds of winning a prize on an instant ticket are 1 in 10, then how come when I bought 10 tickets I didn't win?"
How should I answer this question?
Side note: Even though the website uses the word 'odds' they are actually giving the probability.

You can put this solution on YOUR website!
Because the expected value of buying 10 (or 11) tickets is 1 win; it doesn't guarantee that you will win one ticket. This kind of probability is distributed using a binomial distribution, in which winning 0/11, 1/11, 2/11, etc. have their own probabilities.
