Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 73 people in the 18-21 age bracket and finds that 62 of them respond and 11 refuse to respond. When 303 people in the 22-29 age bracket are contacted, 273 respond and 30 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 responds. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(22-29 or responds) = %
