Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 105 people in the 18-21 age bracket and finds that 89 of them respond and 16 refuse to respond. When 271 people in the 22-29 age bracket are contacted, 243 respond and 28 refuse to respond. Assume that 1 of the 376 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who refused to respond.Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol.P(22-29 or refused) =
