When 292 people in the 22-29 age bracket are contacted, 270 respond and 22 refuse to respond. Assume that 1 of the 380 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) - (Hint: It might be helpful to organize the data into a table first.)
