If np ≥ 5 and nq ≥ 5, estimate P(fewer than 3) with
n =14 and p = 0.4 by using the normal distribution as an
approximation to the binomial distribution; if np < 5 or nq
< 5,
then state that the normal approximation is not suitable. Select
the correct choice below and, if necessary, fill in the answer
box to complete your choice.
A. P(fewer than 3)=
or
B. the normal approximation is not suitable
