Explanation:
There are standard formulae for the mean and standard deviation of a binomial probability distribution.
If you are going to do any significant work with binomial probability distributions you should memorize these:
$\mu =n\cdot p$
$\sigma =\sqrt{n\cdot p\cdot \left(1-p\right)}$
mean: $\mu =10.5$
standard deviation: $\sigma =1.9$
