  • Probability Question with Socks

    Pretend that I have 50 pairs of socks, and each pair is a different color. Suppose all 100 socks are mixed up in a laundry basket. In the dark, I pull out 40 socks atrandom. Part a. What is the probability that I have 20 matching pairs. Part b. What is the probability that I have AT LEAST one matching pair. Part c. What is theprobability that I have EXACTLY k matching pairs. Please leave your answers involving terms like n choose k.My thoughts, obviously, the sample space is 100 choose 40, but where I'm struggling is the actual count of the 3 events. For Part b. it seems simpler to determine thecomplement (no matchings pairs) and then doing 1- the complement. Please help!!
