Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 102 people in the 18-21 age bracket and finds that 87 of them respond and 15 refuse to respond. When 280 people in the 22-29 age bracket are contacted, 246 respond and 34 refuse to respond. Assume that 1 of the 382 people is randomly selected. Find the probability of getting someone in the 18- 21 age bracket or someone who responds. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. (Hint: It might be helpful to organize the data into a table first.)
