Question

Nine qualified applicants apply for a part-time job. If the manager randomly hires 2 of them, what is the probability that he hires the 2 oldest?

Answer 1

There is a `1` in `72` chance that the two oldest will be hired.

Explanation:

The probability of any one the `9` applicants being selected is `1/9`

Once the first has been selected, there are now `8` left fromwhich the second applicant can be chosen.

`P("Oldest, Oldest") =1/9 xx1/8 = 1/72`
