Pollsters are concerned about declining levels of cooperation among persons contacted in surveys.
A pollster contacts 80 people in the 18-21 age bracket and finds that 68 of them respond and 12 refuse to respond.
When 280 people in the 22-29 age bracket are contacted, 253 respond and 27 refuse to respond.
Assume that 1 of the 360 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.
