If np greater than or equals 5np5 and nq greater than or equals 5nq5, estimate Upper P left parenthesis fewer than 4 right parenthesisP(fewerthan4) with nequals=1414

and pequals=0.40.4 by using the normal distribution as an approximation to the binomial distribution; if npless than<5 or nqless than<5, then state that the normal approximation is not suitable
