Question 325396: I am looking for assistance solving this problem:
In a certain lottery, 4 different numbers between 1 and 9 inclusive are drawn at random. These are the winning numbers. If you choose 4 different numbers at random between 1 and 9, what is the probability you will match the winning numbers? Assume that the order of the numbers is unimportant.
Thanks!!

You can put this solution on YOUR website! In a certain lottery, 4 different numbers between 1 and 9 inclusive are drawn at random. These are the winning numbers.

There is only one set of winning numbers.

There are a total of 9C4 = 126 sets of 4 numbers.
------------------------------
P(selecting the winning number set) = 1/126
