Answer 12

The sample proportion in an experiment is found by dividing the number of successes (the binomial random variable) by the number of trials.
Therefore the sample proportion is given by:
\[\large \hat{p}=\frac{X}{n}=\frac{number\ of\ successes}{number\ of\ trials}\]
where\[\large X\ \tilde\\ Bin(n,p)\]
