Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 86 people in the 18-21 age bracket and finds that 73 of them respond and 13 refuse to respond. When 285 people in the 22-29 age bracket are contacted, 258 respond and 27 refuse to respond. Assume that 1 of the 371 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.
