Question 972171: An experiment with equally likely outcomes has a sample space S and an event E, with P(E)=.50 and n(E)=.45. We also know that for another event F in S, P(F)=.4. Find n(F), the number of outcomes in F.
I have tried to start out this problem but feel I am missing something so I cannot start it.
Answers are: 36,35,34,33,32,or none.

I'm assuming you mean n%28E%29=45.
P%28E%29%2Fn%28E%29=P%28F%29%2Fn%28F%29
0.50%2F45=0.4%2Fn%28F%29
n%28F%29=%280.4%2F0.5%29%2845%29
Work that out to get your solution.
