Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 82 people in the 18-21 age bracket and finds that 70 of them respond and 12 refuse to respond. When 259 people in the 22-29 age bracket are contacted, 240 respond and 19 refuse to respond. Assume that 1 of the 341 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who responds.
