Since, the number of ways to select 2 girls is 5C2. Now, 3 boys can be selected in 3 ways. (a) Selection of A and selection of any 2 other boys ( except B) in 5C2 ways (b) Selection of B and selection of any 2 twoother boys ( except A) in 5C2 ways (c) Selection of 3 boys (except A and B ) in 5C3 ways Hence, required number of different teams =5C2(5C2+5C2+5C3)=300
