Ask the student a question, and give any hints about how they should answer this part.
Assuming a binomial distribution for $X$ , {descX}, write down the values of $n$ and $p$.
$X \sim \operatorname{bin}(n,p)$
$n=\; $?
Find $\operatorname{E}[X]$ the expected {descX1}
$\operatorname{E}[X]=$?
Find the standard deviation for the {descX1}
Standard deviation = ?
