Pollsters are concerned about declining levels of cooperation among persons contacted in surveys.
A pollster contacts 76 people in the 18-21 age bracket and finds that 65 of them respond and 11 of them refuse to respond.
When 303 people in the 22-29 age bracket are contacted, 283 respond and 20 refuse to respond.
Assume that 1 of the 379 people is randomly selected.
Find the probability of getting someone in the 18-21 age bracket or someone that does not respond.
