Find the mean of the Binomial distribution $B (4, \frac{1}{3})$.
Answer & explanation
Correct answer: option 2
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 = $np = 4×\frac{1}{3}=\frac{4}{3}$
