I'm trying to calculate the odds for the Powerball.. They draw 5 balls from the numbers 1-59 and then a Powerball from the numbers 1-35. The posted odds for getting just the Powerball right are 1 in 55.41. I can't get this number. When I tried I said the probability of the firstwhite ball not being correct is 54/59 the next white ball was 54/58, and etc. So the individual odds I used were 54/59, and 54/58, and 54/57, 54/56, 54/55, and 1/35. When I multiply these I don't get the right answer.. What did I do wrong?
