Answer
Let N denote employees happy with their jobs, and M denote employees who are not happy with their jobs.
Work Step by Step
In a sample of two employees, the number who is happy with their jobs can be 0 (given by MM), 1 (given by NM or MN), or 2 (given by NN). Thus, x can assume any of three possible values: 0,1 and 2. The probabilities of these three outcomes are calculated as follows:
P(0) = P(MM) = 0.4225
P(1) = P(MN or NM) = P(MN) + P(NM) = .2275+.2275 = .4550
P(2) = P(NN) = .4225
Using these probabilities, we can write the probability distribution of x as in the table below.
