A pollster contacts 84 people in the 18-21 age bracket and finds that 71 of them respond and 13 refuse to respond. When 288 people in the 22-29 age bracket are contacted, 272 respond and 16 refuse to respond. Assume that 1 of the 372 people is randomly selected. Find the probability of getting someone in the 18-21 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(18-21 or agreed) = 1.5 X (Hint: It might be helpful to organize the data into a table first.)
