Answer:oThis is just the (27 choose 2) part of the binomial equation.It does not use any p valuesso there is no need to include those.oIf you have 27 things, you can pair them up 351 different ways.Homework Problems:Situation: It is a cold, dark, and stormy winter morning. Your boss has called a 5a.m. meeting before she leaves to catch a flight to the Bahamas for her vacation, and there is a poweroutage. Your alarm does not go off and you sit up in bed with a fright at what you guess is about 4:45a.m. You are trying frantically to get dressed andyou need to reach into your sock drawer to get twomatching socks in the dark.Naturally, your mind wanders to solving probability equations. Your sockdrawer contains 20 total socks which consist of 10 matched pairs of socks. All of them are only black orwhite and they are loose, disorganized randomly, and not bound together. This means you have 10 blacksocks and 10 white socks in your disorganized drawer. You do not have a light source because your phonedid not charge and you cannot find a flashlight or a candle. You are completely in the dark! You have toget dressed and go! You have to math fast!1.Think for a minute and describe your optimal strategy for solving this problem in 50 words orless.For the sock problem, we need at least 1 successful trial to accomplish the goal of havinga matched pair of socks.So in that sense, the trial needs to be repeated until success.However, time is important so we can’t waste time on extra trials. We need the minimumnumber of trials to get one success.In terms of the binomial probability equation, it looks as ifwe are starting withthe ending value of 100% and solving for n. Where number of successesk= 1 and p is probability of picking either a pair of white socks or a pair of black socks p=.474,which would be a lot of math. Or you could just take 3 socks.
