it can be done in 2 ways

Answer 2

Answer:

1260

There are 36 teachers and every one has equal chance of being selected as a principal.

Hence, the principal can be appointed in 36 ways. When one person is appointed asprincipal, we are left with 35 teachers. Out of these 35 teachers, we have to select one vice-

principal. So a vice-principal can be selected in 35 ways. Hence, the number of ways in which

a principal and vice-principal can be selected = 36 x 35 =1260.
