What is the probability that a person selected at random in that town will be a woman? Because  women constitute 60 percent of the total population, the probability is 0.60. What is the probability that a person 70 years of age or older, selected at random, will be a woman?  This question is different because the probability of  A  (being a woman) given  B  (the person in  question being 70 years of age or older) is now conditional upon

Unformatted text preview: B (being 70 years of age or older). Because women number 20 out of the 25 people in the 70-or-older group, the probability of this latter question is , or 0.80. Conditional probability is found using this formula: which is read: The probability of A given B equals the probability of A and B divided by the probability of B . The vertical bar in the expression A|B is read given that or given ....
