Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 83 people in the 18-21 age bracket and finds that 70 of them respond and 13 refuse to respond. When 268 people in the 22-29 age bracket are contacted, 238 respond and 30 refuse to respond. Assume that 1 of the 351 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who agreed to respond.
