1. Of all failures of a certain type of computer hard drive, it is determined that in 20% of them only thesector containing the file allocation table is damaged, in 70% of them only nonessential sectors aredamaged, and in 10% of the cases both the allocation sector and one or more nonessential sectors aredamaged. A failed drive is selected at random and examined.What is the probability that the allocation sector is damaged?b. What is the probability that a nonessential sector is damaged?c. If the drive is found to have a damaged allocation sector, what is the probability that somenonessential sectors are damaged as well?d. If the drive is found to have a damaged nonessential sector, what is the probability that theallocation sector is damaged as well?e. If the drive is found to have a damaged allocation sector, what is the probability that nononessential sectors are damaged?f. If the drive is found to have a damaged nonessential sector, what is the probability that theallocation sector is not damaged?2. A system consists of four components connected as shown in the following diagram:ACOBAssume A, B, C, and D function independently. If the probabilities that A, B, C, and D fail are 0.10, 0.05,0.10, and 0.20, respectively, what is the probability that the system functions?

A pollster contacts 73 people in the 18-21 age bracket and finds that 62 of them respond and 11 refuse to respond. When 303 people in the 22-29 age bracket are contacted, 273 respond and 30 refuse to respond. Assume that 1 of the 376 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who responds.Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol.P(22-29 or responds) = %
