The probability of winning the lottery is .11. If you buy 5 tickets (one each month), what is the probability that you will win the lottery *at least one time*?

The probability that you will NOT win in any given month is .89. So the probability that you will not win at all in the 5 months is (.89)^5 = .56. This means that the probability that you will win once or more is 1 - .56 = .44.
PRETTY UNLIKELY BUT ITS POSSIBLE I MEAN PEOPLE HAVE WON BEFORE SO ID SAY 1 IN 100,000,000
like a million to 1......not very good chances eh?
