Suppose a biological cell contains 400 genes. When treated radioactively the probability that
Anton [14]
Let X\sim\mathrm{Bin}(400,0.006) be the random variable representing the number of genes that do get mutated. Here \mathrm{Bin}(n,p) denotes a binomial distribution with parameters n (total number of genes) and p (probability of mutation).

Then the probability that *at most* 4 genes get mutated is

\mathbb P(X\le4)=\displaystyle\sum_{x=0}^4\mathbb P(X=x)

where

\mathbb P(X=x)=\begin{cases}\dbinom{400}x0.006^x(1-0.006)^{400-x}&\text{for }x\in\{0,1,2,\ldots,400\}\\\\0&\text{otherwise}\end{cases}

You should find that

\mathbb P(X\le4)\approx0.9047
