Question 1199737: Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 93 people in the 18-21 age bracket and finds that 79 of them respond and 14 refuse to respond. When 254 people in the 22-29 age bracket are contacted, 225 respond and 29 refuse to respond. Assume that 1 of the 347 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who refused to respond.
Report the answer rounded to 4 decimal place accuracy.
P(22-29 or refused) =
