Explanation / Answer
n=4
r =2
p=96% =96/100 =0.96
q =1-p=0.04
probability in Binomial distribution P(x=r)= nCr pr (1-p)n-r
the probability that exactly 2 of the workers interviewed are union members=P(X=2)
=4C2(0.96)2(0.04)2
=0.0088
the probability that exactly 2 of the workers interviewed are union members=0.0088
