1. AssumeX

Xhas a binomial distribution. Use the binomial formula, tables, or technology to calculate the probability of the indicated event:

a.n=14,p=0.7

n=14,p=0.7

P(X12)=

(Round to four decimal places if necessary)

b.n=12,p=0.35

n=12,p=0.35

P(X<3)=

(Round to four decimal places if necessary)
