As there are 12 socks in total, and we are taking 2 of them, there would be 12C2 = 66 ways to do this. Therefore the probability of getting a matched pair would be 6/66 or 1/11 ( 0.090909...) 2. One sock is pulled and then a second sock is pulled. The probability of the second sock matching the first sock pulled can be found by the simple probability formula:
As you can see, regardless of how we approach this problem, we get the same probability. Hope this helps,
