Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 95 people

in the 18-21 age bracket and finds that 81 of them respond and 14 refuse to respond. When 287 people in the 22-29 age bracket are contacted, 269 respond and 18 refuse to respond. Assume that 1 of the 382 people is randomly selected. Find the probability of getting someone in the 18-21 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(18-21 or responds) = %
