Hi,
Note: The probability of x successes in n trials is: 
P = nCx* {{{p^x*q^(n-x)}}} where p and q are the probabilities of success and failure respectively. 
In this case p = .482 & q(rotton) = .518  and n = 5  nCx = {{{n!/(x!(n-x)!)}}}
Let X represent the number of apples that are NOT rotten. 
P(X = 0) = 5C0(.482)^0(.518)^5
P(X = 1) = 5C1(.482)^1(.518)^4
P(X = 2) = 5C2(.482)^2(.518)^3
P(X = 3) = 5C3(.482)^3(.518)^2
P(X = 4) = 5C4(.482)^4(.518)^1
P(X = 5) = 5C5(.482)^5(.518)^0
