Explanation:
Detailed explanation-1: -The probability of picking a pair of white socks is also 1/2 of 11/23, meaning in order to get the probability of picking any matching pair, you add these two together. The final probability of picking a matching pair of socks is 11/23, or 47.8 percent.
Detailed explanation-2: -Picking the first sock of the two with the same color has the probability of 2/6, and therefore picking the second sock with the same color has a probability of (2−1)/(6−1)=1/5 respectively.
Detailed explanation-3: -Either Both Blue must be drawn or Both Red must be drawn. 2 ways. Hence, Required Probability=2/6=1/3.
