globaldesi · Answer

John is always selected so from rest 9 we have to select 2
thus 
9C2 = 36
E

CAMANISHPARMAR · Answer

Since John is already selected, we have to selected only two more persons from 9. Therefore the answer is 9C2 = 36.

Option E is the correct answer.

CrackverbalGMAT · Answer

A team of 3 players needs to be selected in which John is definitely going to be there. So, effectively, only two players have to be selected from 9 players.

Number of ways of selecting ANY 2 players out of 9 players =  9_C_2  = 9 * 8 / 2 = 36 ways.
 The correct answer option is E .

Of n objects, if r objects have to be selected such that ‘x’ objects should always be a part of the selection, the number of ways of doing this =  (n-x)_C_(r-x) 
Hope that helps!

MathRevolution · Answer

We don't have to select John, as he will be always on the team.

The remaining 2 players will be selected out of 9 available players:  ^9{C_2} = 36
