Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 101 people in the 18-21 age bracket and finds that 86 of them respond and 15 refuse to respond. When 243 people in the 22-29 age bracket are contacted, 209 respond and 34 refuse to respond. Assume that 1 of the 344 people is randomly selected. Find the probability of getting someone in the 22-29 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(22-29 or agreed) = %
