An aircraft seam requires 24 rivets. The seam will have to be reworked if any of these rivets is defective. Suppose rivets are defective independently of one another, each with the same probability. (Round your answers to four decimal places.) (a) If 16% of all seams need reworking, what is the probability that a rivet is defective? (b) How small should the probability of a defective rivet be to ensure that only 5% of all seams need reworking?

Two pumps connected in parallel fail independently of one another on any given day. The probability that only the older pump will fail is 0.25, and the probability that only the newer pump will fail is 0.15. What is the probability that the pumping system will fail on any given day (which happens if both pumps fail)? (Round your answers to four decimal places.) I had put 1/4 and 1/2 however these were proven to be incorrect?

Problem Background Managing the operations of the air group on an aircraft carrier is a complex and dangerous task. These carrier operations involve launching and landing (recovering) aircraft. Aircraft require an Aircrew. The Aircrew accumulate experience as they conduct more missions. Missions require a certain level of expertise. This expertise is known as the status of the Aircrew. When an aircraft is first created, it is placed on the carrier flight deck. An Aircrew will (can) be created and assigned...

1.) Accrotime is a manufacturer of quartz crystal watches.
Accrotime researchers have shown that the watches have an average
life of 30 months before certain electronic components deteriorate,
causing the watch to become unreliable. The standard deviation of
watch lifetimes is 10 months, and the distribution of lifetimes is
normal.
(a) If Accrotime guarantees a full refund on any defective watch
for 2 years after purchase, what percentage of total production
will the company expect to replace?
(b) If Accrotime...
