APSTAT-NKVGOY

What are the mean and variance of the binomial distribution with $n$ number of trials and $P$ probability of success?

A

Mean: $nP$

Variance: $n(P)(1-P)$

B

Mean: $P$

Variance: $\cfrac{ n(P) } { (1-P)}$

C

Mean: $P$

Variance:$\cfrac{ (P)}{[\sqrt{n}]}$

D

Mean: $nP$

Variance: $\cfrac{(sigma)}{[\sqrt{n}]}$

E

Mean: $\mu$

Variance: $\sqrt{(n)(P)($1$-P)}$
