Step-by-step explanation:
well, we need to multiply the possibilities of forming a group of 2 boys out of 6 with the possibilities to firm a group of 2 girls out of 5.
the first is 6 over 2
6! / (2! × (6-2)!) = 6×5/2 = 3×5 = 15
the second one is 5 over 2
5! / (2! × (5-2)!) = 5×4/2 = 5×2 = 10
so, these 15 possibilities combined with the 10 possibilities makes
15×10 = 150
possibilities to form this committee.
