Given a Binomial Distribution with N Trials and Probability P $n p \geq 5 \text { and } n ( 1 - p ) \geq 5$

Given a binomial distribution with n trials and probability p of a success on any trial, a conventional rule of thumb is that the normal distribution will provide an adequate approximation of the binomial distribution if:

A) $n p \geq 5 \text { and } n ( 1 - p ) \geq 5$
B) $n p \leq 5 \text { and } n ( 1 - p ) \leq 5 \text {. }$
C) $n p \geq 5 \text { and } n ( 1 - p ) \leq 5$
D) $n p \leq 5 \text { and } n ( 1 - p ) \geq 5$
