Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 76 people in the 18-21 age bracket and finds that 65 of them respond and 11 refuse to respond. When 274 people in the 22-29 age bracket are contacted, 252 respond and 22 refuse to respond. Assume that 1 of the 350 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. P(22-29 or agreed) = (Hint: It might be helpful to organize the data into a table first.)
