Question
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 281 people in the 22-29 age bracket are contacted, 254 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.
P(18-21 or agreed)=P(18-21 or agreed)=
