Question 883731: Can someone help me please with; Calculate the (modeled) probability P(E) using the given information, assuming that all outcomes are equally likely.
n(S) = 25, n(E) = 5
P(E) = ?

%22P%28E%29%22%22%22=%22%22%22n%28E%29%22%2F%22n%28S%29%22

In probability theory "OUT OF" means "OVER"

The probability is 5 OUT OF 25, or "5 OVER 25" or 5%2F25 which reduces
to 1%2F5 which means that one-fifth of the time E will happen.
