Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 79 people in the 18-21 age bracket and finds that 67 of them respond and 12 refuse to respond. When 294 people in the 22-29 age bracket are contacted, 271 respond and 23 refuse to respond. Assume that 1 of the 373 people is randomly selected. Find the probability of getting someone in the 18-21 age bracket or someone who does not respond. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(18-21 or does not respond) = (Hint: It might be helpful to organize the data into a table first.)
