PROBLEM 6E

A researcher finds that, of 982 men who died in 2002, 221 died from some heart disease. Also, of the 982 men, 334 had at least one parent who had some heart disease. Of the latter 334 men, 111 died from some heart disease. A man is selected from the group of 982. Given that neither of his parents had some heart disease, find the conditional probability that this man died of some heart disease.

Step-by-Step Solution:

Step 1 of 3:

Given the information states that, 982 men who died in 2002, 221 died from some heart disease. Also, of the 982 men, 334 had at least one parent who had some heart disease. Of the latter 334 men, 111 died from some heart disease.

We need to find the conditional probability that this man died of some heart disease.

Step 2 of 3:

 At least one parent who had some heart disease Yes No Total Died 111 221-111=110 221 Not 334 - 111 = 223 761-223 = 538 982-221=761 Total 334 982 - 334 = 648 982

Therefore the conditional distribution is

P(died/neither of his parents) =

= 0.169753.
