Open Question: I have a probability problem that no one I know can solve?
May/110
For a particular lottery, the winning numbers are selected by a
machine that randomly chooses 5 table-tennis balls from among
45, numbered 1 to 45. The lottery pays off if you match 5, 4,
or 3 of the numbers.
What is the probability that you will match,
exactly 4 of the 5 winning numbers?
We already know the answer is 200/1,221,759 but the question is how do you get to that number?
