vredina [299]

Answer: 0.1699

Step-by-step explanation:

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

Sample size : n= 5

Binomial probability distribution formula :

P(X=x)= \ ^nC_xp^x(1-p)^x

The probability that exactly 4 of the workers interviewed are union members :-

P(X=4)=^5C_4(0.96)^4(1-0.96)^1\\\\=(5)(0.96)^4(0.04)\\\\=(5)(0.84934656)(0.04)\\\\=0.169869312\approx0.1699

Required probability = 0.1699
