If np ≥5 and nq ≥5, estimate P(fewer than 3) with n = 13 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.
OA. P(fewer than 3)=
(Round to four decimal places as needed.)
OB. The normal approximation is not suitable.
