Question

Company A has 400 employees and Company B has 500 employees. Among these employees, there are 50 married couples, each consisting of an employee from A and an employee from B. If 1 employee is to be selected at random from each company, what is the probability that the 2 employees selected will be a married couple?

Answer 1

Answer:0,0025

Step-by-step explanation:

P(select a married couple) = P(person selected from Company A is one of the 50 with spouse at Company B) x P(person selected from Company B spouse of person already selected from Company A)

Now you can substitute the respective probabilities .

= (50/400) x (1/500)

= 0,0025
