Q1. In a drawer there are 4 white socks, 3 blue socks and 5 grey socks. Two socks are picked randomly. What is the possibility that both the socks are of same color?
Answer: 19/66
Explanation: Favourable pairs (same colour) = C(4,2) + C(3,2) + C(5,2) = 6+3+10 = 19; total pairs = C(12,2) = 66, giving probability 19/66.
