Probability is expressed as
number of favorable outcomes/number of total outcomes
From the information given,
number of men = 3
number of women = 5
total number of men and women = 3 + 5 = 8
The favorable outcome in this case is the event of selecting a man. Therefore,
The probability of selecting the first man = 3/8
We are left with 2 men and 7 people. The probability of selecting the second man is 2/7
We are left with 1 man and 6 people. The probability of selecting the third man is 1/6
Therefore, the the probability that all men will be interviewed first is
3/8 x 2/7 x 1/6 = 0.018
the the probability that all men will be interviewed first is 0.018
