Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 78 people in the 18-21 age bracket and finds that 66 of them respond and 12 refuse to respond. When 267 people in the 22-29 age bracket are contacted, 249 respond and 18 refuse to respond. Assume that 1 of the 345 people is randomly selected. Find the probability of getting someone in the 18-21 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.prob = %
