Question

$3$ dice are thrown simultaneously. Let $X$ be the random variable of number of sixes obtained. Construct the probability distribution table for $X$ and show that $X$ is a discrete random variable. Find $\mathrm{E}\left( X \right)$ and $\mathrm{Var}\left( X \right)$.

Accepted Answer

$	ext{E}\left( X ight)=\frac{1}{2}$; $	ext{Var}\left( X ight)=\frac{5}{12}$
