Question: Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 99 people in the 18-21 age bracket and finds that 54 of them respond and 45 refuse to respond. When 297 people in the 22-29 age bracket are contacted, 277 respond and 20 refuse to respond. Suppose that one of the 396 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who responded.
