Find the mean of the Binomial distribution $B (4, \frac{1}{3})$. |
$\frac{1}{3}$ $\frac{4}{3}$ $\frac{2}{3}$ $\frac{5}{3}$ |
$\frac{4}{3}$ |
The correct answer is Option (2) → $\frac{4}{3}$ The parameters of the given binomial distribution are 4 and $\frac{1}{3}$ i.e. $n = 4$ and $p =\frac{1}{3}$ The mean of the binomial distribution = $np = 4×\frac{1}{3}=\frac{4}{3}$ |
