Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 89 people in the 18-21 age bracket and finds that 76 of them respond and 13 refuse to respond. When 292 people in the 22-29 age bracket are contacted, 274 respond and 18 refuse to respond. Assume that 1 of the 381 people is randomly selected. Find the probability of getting someone in the 18-21 age bracket or someone who refused to respond.
