Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 77 people in the 18-21 age bracket and finds that 65 of them respond and 12 refuse to respond. When 298 people in the 22-29 age bracket are contacted, 271 respond and 27 refuse to respond. Assume that 1 of the 375 people is randomly selected. Find the probability of getting someone in the 18-21 age bracket or someone who agreed to respond. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(18-21 or agreed) = %
