Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 79 people in the 18-21 age bracket and finds that 67 of them respond and 12 refuse to respond. When 263 people in the 22-29 age bracket are contacted, 240 respond and 23 refuse to respond. Assume that 1 of the 342 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who responds. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(22-29 or responds) = %
