You flip a coin 25 times. Let X; be the Bernoulli random variable indicating if the i-th coin flip lands on a head. 1, X; = | 0, otherwise. if the i-th coin flip lands on a head, Assume that the probability of each coin flip landing on a head is 0.5, and that the 25 coin flips are independent. (a) Are X1, X2, ..., X25 i.i.d. (independent and identically distributed)? Briefly explain. (b) Find the expected value of X1 + X, + .…+X25 ... 25 (c) Find the variance of X. (Hint: first compute the variance of X¡.)

A report from the Department of Agriculture has shown that 35% of the produce in supermarkets has been genetically modified (labeled a GMO). A simple random sample of 12 different pieces of produce are selected. What is the probability that exactly 4 of the pieces of produce has been genetically modified (labeled a GMO)? Show how you calculated your result here (type in what you typed on your calculator or computer, the function used on the calculator/computer with value input, etc) Calculation: __________ Now type in your final simplified or rounded answer, if necessary round your answer to four decimal places. P(exactly 4 are GMO) =__________
