Refer to given Exercise. Which method of finding probabilities do you think was used to find the "90 percent chance" and "37 percent chance"? Explain.
Exercise
According to Krantz (1992, p. 102), "[In America] women between the ages of 20 and 24 have a 90 percent chance of being fertile while women between 40 and 44 have only a 37 percent chance of bearing children [i.e., being fertile]." Define appropriate events, and write these statements as conditional probabilities, using appropriate notation.
