Book PS # 7 Round all of your final answers to four decimal places if necessary. #1) Suppose that A and B are two independent events with P ( A ) = 0.2 and P ( B ) = 0.2. a. What is P ( A and B )? b. What is P ( A or B )? c. What is P ( A or B c )? #2) Disease Y a disease caused by a sex-linked recessive mutation. A son of a carrier of disease Y can get disease Y from the carrier. As many as 3/10 of disease Y cases, however, are due to spontaneous mutations in sons of mothers who are not carriers. Jessica has one son, who has disease Y. In the absence of other information, the probability is 0.3 that the son is the victim

Unformatted text preview: of a spontaneous mutation and 0.7 that Jessica is a carrier. There is a screening test called the CK test that is positive with probability 0.8 if a woman is a carrier and with probability 0.1 is she is not. Jessica’s CK test is positive. Find the conditional probability that Jessica is a carrier given that her CK test is positive. Round your final answer to four decimal places if necessary.
