a shipment contains 1000 fuses. for each fuse the probability is 0.05 that it is defective. the effectiveness of any fuse is independent of the effectiveness of any other fuse. let ???????? be the random variable that counts the number of defective fuses in the shipment. (a) calculate ????????[4???????? 10] (b) use a summation (∑) formula to express PP(30 ≤???????? ≤60). do not compute the decimal answer. leave it in formula form. (d) 10 fuses from the shipment are randomly selected. what is the probability the number of defective fuses is exactly 2 in the set of 10 randomly selected fuses?
