I have been able to figure out everything on my assignment but this one. Can anyone help?
Five numbers are to be picked, without repetition from 44 numbers to determine the winner of the Fortune Five game in the state lottery. If the order of the numbers is insignificant, how many different ways can a winning quintuple be selected? What is the probability of winning?
Answered by Reiny
The number of ways to choose 5 out of 44 numbers is
C(44,5) = 44!/(5!39!) = 1086008

So the prob of winning is 1/1086008
