Given : The proportion of workers employed by the university belong to the workers' union=0.96

Let x be a binomial variable that represents that worker belongs to the workers' union.

Sample size : n= 4

$P(x=3)=^4C_3(0.96)^3(0.04)^1\\\\=(4)(0.96)^3(0.04)=0.14155776$

[Binomial probability formula : P(X=x)=^nC_x(p)^x(1-p)^{n-x}]

Hence, the probability that exactly 3 of the workers interviewed are union members $=0.14155776$
