(a) Find the probability that both adults say Franklin Roosevelt was the best president since World War I. The probability that both adults say Franklin Roosevelt was the best president since World War Il is (Round to three decimal places as needed.) (b) Find the probability that neither adult says Franklin Roosevelt was the best president since World War II. The probability that neither adult says Franklin Roosevelt was the best president since World War Il is (Round to three decimal places as needed.) (c) Find the probability that at least one of the two adults says Franklin Roosevelt was the best president since World War I. The probability that at least one of the two adults says Franklin Roosevelt was-the best president since World War Il is (Round to three decimal places as needed.)

A study tracked a large group of people for 10 years. At the start of the study, 20% were heavy smokers (H), 30% were light smokers (L), and 50% were non-smokers (N). The interest of the study was whether the people in the study died during the study (D) or not die (Dc ). The probability that a light smoker died during the study was twice that of the probability of a non-smoker dying. Also, the probability that light smoker died during the study was half that of the probability of a heavy smoker dying. A randomly selected person from the study died during the study. What is the probability that this person was a heavy smoker (given they died, what is the probability they were a heavy smoker H)?

Based on a study from the Chronicles of Flippin'' Awesomeness, the probability that Napoleon and Pedro make it to their first period class on time is 0.37.  The probability that Napoleon and Pedro catch the bus is 0.66. However, the probability that they make it to their first period class on time, given that they catch the bus is 0.61.  What is the probability that Napoleon and Pedro catch the bus and make it to their first period class on time?

Based on a study from the Chronicles of Flippin'' Awesomeness, the probability that Napoleon and Pedro make it to their first period class on time is 0.45.  The probability that they make it to their first period class on time, given that they catch the bus is 0.71.  The probability that Napoleon and Pedro catch the bus and make it to their first period class on time is 0.50.  What is the probability that Napoleon and Pedro catch the bus?
