Question

Find the mean of the binomial distribution $B(4,\frac{1}{3})$.

Answer 1

The give binomial distribution is $\left(4,\frac{1}{3}\right)$

therefore,

n$=4$ and p$=\frac{1}{3}$

the expert value or mean $\mu =np$

$=4\times \frac{1}{3}$

Hence,

the mean of the binomial distribution is

$=\frac{4}{3}$
