A particular system in a space vehicle must work properly in order tor it to gal accau. earth's atmosphere. One component of the system operates successfully only 85% of the time. To increase the reliability of the system, four of the components are installed in such a way that the system will operate successfully if at least one component is working. What is the probability that the system will fail? Assume the components operate independently.

Suppose you have just received a shipment of 28 modems. Although you don't know this, 4 of the modems are defective. To determine whether you will accept the shipment, you randomly select 9 modems and test them. If all 9 modems work, you accept the shipment. Otherwise, the shipment is rejected. What is the probability of accepting the shipment? The probability of accepting the shipment is (Round to four decimal places as needed.)
An organic beverage company manufactures a lot of 500 canisters of mango concentrates. This lot contain 5 that are rejects. Two are tested, at random, without replacement from the lot. What is the probability that both canisters are rejects? Then, what is the probability that the third one selected is a reject given that the first and second ones selected were rejects?

A boy uses a homemade metal detector to look for valuable metal objects on a beach. The machine isn't perfect-it identifies only 98% of the metal objects over which it passes, and it identifies 4% of the nonmetallic objects over which it passes. Suppose that 25% of the objects that the machine passes over are metal. Find the probability that the boy has found a metal object when he receives a signal from the machine. Show your work.
less than the maximum allowable load for the aircraft. The aircraft can carry 37 passengers, and a flight has fuel and baggage that allows for a total passenger load of 5,957 lb Before every flight, the pilot must verify that the total weight of the load = 161 lb. What is the probability that the aircraft is overloaded? Should the pilot 5,957 Ib. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 37 take any action to correct for an overloaded aircraft? Assume that weights men are normally distributed with a mean of 179.9 lb and a standard deviation of 38.8. The probability is approximately. (Round to four decimal places as needed.) Should the pilot take any action correct for an overloaded aircraft? O A. No. Because the probability is high, the aircraft is safe to fly with its current load. O B. Yes. Because the probability is high, the pilot should take action by somehow reducing the…
