Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 82 people in the 18-21 age bracket and finds that 70 of them respond and 12 refuse to respond. When 259 people in the 22-29 age bracket are contacted, 240 respond and 19 refuse to respond. Assume that 1 of the 341 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who responds.

A national sports equipment co-op is going to conduct a survey of its members. It knows from collecting data when members join that 68% of them identify as male. Assuming the total number of members is very large and 200 of them are randomly selected to take the survey, what’s the chance less than 60% of these randomly chosen members identify as male?

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 102 people in the 18-21 age bracket and finds that 87 of them respond and 15 refuse to respond. When 249 people in the 22-29 age bracket are contacted, 220 respond and 29 refuse to respond. Assume that 1 of the 351 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who responds. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol.
