Problem 40P

A town contains 4 people who repair televisions. If 4 sets break down, what is the probability that exactly i of the repairers are called? Solve the problem for i = 1,2,3,4. What assumptions are you making?

Solution

Step 1 of 5

We have to find the probability for i=1, 2, 3, 4 repairers to repairing 4 televisions

No.of televisions are 4

And no.of repairers are 4

Total no.of ways of getting repair is 44 =256
