Example 3.16 Cell Phone Features (Multiplication Rule) When the conditional probability of text messaging, given photo capability, 0.65 P(AB) - 0.8125 0.80 is multiplied by the probability of photo capability, we have the joint probability of both messaging and photo capability: P(ANB) (0.8125)(080) 0.65 In the following example we see an interesting application of the multiplication rule of probabilities. We also lie together some ideas introduced previously Example 3.17 Sensitive Questions (Multiplication Rule) Suppose that a survey was carried out in New York, and each respondent was faced with the following two questions a is the last digit of your Social Security number odd? b.
