Suppose that 15% of emperor moths have damaged wings. A biologist examines random samples of 9 moths on a daily basis. a) What is the expected value for the number of moths with damaged wings that the biologist finds each day? b) Set up the equation you would use to determine the probability that the biologist finds more than six moths with damaged wings on Tuesday. (You do not have to solve the equation; simply provide the formula and then plug in the values for the variables.) c) What is the probability that four of the moths the biologist examines on Tuesday have damaged wings?
