Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 100 people in the 18-21 age bracket and finds that 85 of them respond and 15 refuse to respond. When 254 people in the 22-29 age bracket are contacted, 223 respond and 31 refuse to respond. Assume that 1 of the 354 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. prob = %
