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 4 workers (chosen at random) at the university to get their opinions on the strike. what is the probability that exactly 3 of the workers interviewed are union members?

0.14155776

Step-by-step explanation:

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

[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

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

answer: 4 (:
