Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 90 people in the 18-21 age bracket and finds that 76 of them respond and 14 refuse to respond. When 272 people in the 22-29 age bracket are contacted, 242 respond and 30 refuse to respond. Assume that 1 of the 362 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who responds.
