14. The table summarizes results from 978 pedestrian deaths that were caused by automobile accidents.

Driver Intoxicated?	Pedestrian Intoxicated?
Yes	No
Yes	50	67
No	281	580

If one of the pedestrian deaths is randomly selected, find the probability that the driver was not intoxicated but the pedestrian was. Please enter a decimal to 4 places. 15.

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 85 people in the 18-21 age bracket and finds that 72 of them respond and 13 refuse to respond. When 288 people in the 22-29 age bracket are contacted, 260 respond and 28 refuse to respond. Assume that 1 of the 373 people is randomly selected. Find the probability of getting someone in the 18-21 age bracket or someone who does not respond. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(18-21 or does not respond) = % (Hint: It might be helpful to organize the data into a table first.)

16. Luke buys a bag of cookies that contains 4 chocolate chip cookies, 6 peanut butter cookies, 9 sugar cookies and 7 oatmeal raisin cookies. What is the probability that Luke randomly selects a chocolate chip cookie from the bag, eats it, then randomly selects another chocolate chip cookie? (Round your answer to 4 decimal places.)
