Question

A debate team of 4 is to be chosen from a class of 37. There are two twin brothers in the class. How many possible ways can the team be formed which will include both of the twin brothers?

Answer 1

Answer :

No.of people in class = 37

Total no.of twin brothers = 2

No.of persons choosen = 4(including twin brothers)

So remaining persons to be choosen = 4 - 2 = 2

i.e 2 numbers need to be choosen out of 35.

Therefore,

The possible ways can the team be formed which will include both of the twin brothers is

i.e = 595

So,there are 595 possible ways can the team be formed which will include both of the twin brothers.
