it's been a long time since I thought about questions like this, but, as a lead-in to a study, a client has asked the following question which he thinks he understands and says is related to where he wants to go: during a consecutive period of 120 days, if it rains on 7 days and my client wears a hat on 4 days (these are independent of any knowledge of the weather), what is the probability that it will rain on 3 of the days on which he is wearing a hat? my client swears that this is not a homework problem for him or his wife or one of their kids!
