Question 934905:
The workers' union at a particular university is quite strong. About 96% of all workers employed by the university belong to the workers' union. Recently, the workers went on strike, and now a local TV station plans to interview 5 workers (chosen at random) at the university to get their opinions on the strike. What is the probability that exactly 4 of the workers interviewed are union members?
Round your response to at least three decimal places

Round your response to at least three decimal places
---------------
Binomial Problem with n = 5 and p(union) = 0.96
--------------
P(x = 4) = 5C4*0.96^4*0.06 = binompdf(5,0.96,4) = 0.1700
