Events with two possible outcomes are modelled by the following equation: if the probability of success is p, you have n trials, and X is the random variable representing the number of times the event with probability p happens, you have

\displaystyle P(X=k) = \binom{n}{k} p^k (1-p)^{n-k}

Now, you want X=0 (i.e. the event never happens). So, you have

\displaystyle P(X=0) = \binom{n}{0} p^0 (1-p)^{n-0} = (1-p)^n
