Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 74 people in the 18-21 age bracket and finds that 63 of them respond and 11 refuse to respond. When 282 people in the 22-29 age bracket are contacted, 252 respond and 30 refuse to respond. Assume that 1 of the 356 people is randomly selected.


Required:

Find the probability of getting someone in the 18-21 age bracket or someone who agreed to respond.
