Suppose that 40% of fruit flies possess a certain gene. We will randomly select fruit flies until we have found 3 flies with the gene. Let Y = 0, 1, 2, 3, 4, 5, . . . be the random variable defined as the number of flies we must be select so that we obtain three flies with the gene. If f(y) denotes the probability function for Y, find f(7). O 0.0838 O 0.1244 O 0.1529 O 0.1045 O 0.1382
