Question

In a group of twelve people, four had been selected for a transfer. If two of the twelve are selected, what is the probability that both of those selected are selected for a

transfer?

Answer 1

1/11

Explanation:

The probability the first person has been selected for transfer is 4/12.

The probability the second person has been selected for transfer is 3/11.

So the probability of both is 4/12 × 3/11 = 1/11.
