- 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!!

- how many different ways
A spymaster has a network of 11 operatives whom he pays out of a slush fund containing $24000. For accounting reasons, his service requires him to use up his entirefund and to pay his operatives in integer multiples of $1000.(a) How many different ways can he pay his operatives?(b) Since an unpaid operative is unreliable, the spymaster decides that every operative will get at least $1000. With this rule, how many different ways can he pay hisoperatives?How do I approach this problem?
