QUESTION 3. Research in a town shows that if it rains on any one day then the probability that it will rain the following day is 25%. If it does not rain one day then the probability that it will rain the following day is 12%. Starting on a Monday and given that it rains on that Monday: (a) Draw a probability tree diagram to illustrate the information, and show the probability on ALL of the branches. (b) Determine the probability that it will rain on the Wednesday of that week.
QUESTION 15 Suppose that in a given town, 60% of the population is under age 40 (event A). It is found that the proportion of residents under age 40 who support mandatory inoculation is 0.72. The proportion of residents over age 40 who support mandatory inoculation is 0.52. Let event B = support mandatory inoculation. Define the term probability by choosing the correct answer below. Probability is the long-run event. Probability is the frequency of an event. Probability is the fraction of times an event occurs in n independent replications of an experiment. Probability is the long-run relative frequency of an event.
