(a) Find the probability that this baby wombat won’t get the zoomies for at least 16 minutes after you start watching it. (b) Find the probability that if the baby wombat hasn’t gotten the zoomies within 14 minutes, it won’t have gotten them within half an hour. (c) Find out how long you should expect it to take before the baby wombat gets the zoomies for the fourth time.

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)?
