080324 value: To find the expected value (or long-term average) of an experiment, multiply the value of each outcome of the experiment by its probability and add the results. e.g fluff friends bet 5 munny on Jerry Jerry Tom Mph: 10 Mph: 65 Payoff: 20 times Payoff: 1.5 times Odds: 0.02:0.98 Odds: 0.98:0.02 outcome Winning Losing Expected value=95*0.02-5*0.98=-3 Cystic Fibrosis: the most common inherited disease; the child's lungs and intestines and pancreas will be clogged with thick mucus; there is no cure Most patients with cystic fibrosis die of chronic lung disease; most died in early childhood. In 1989, a team of Canadian and American doctors announced the discovery of the gene that is reponsible for most cases of cystic fibrosis. As a result of that discovery, a new therapy for cystic fibrosis is being developed. Cystic fibrosis occurs in about 1 out of every 2000 births in the Caucasian population and only in about 1 in 250,000 births in the non-Caucasian population. It is one the of most common inherited diseases in North America. One in 25 Americans carries a single gene for cystic fibrosis. Children who inherit two such genes develop the disease; that is, cystic fibrosis is recessive. There are tests that can be used to determine whether a person carries the gene. However, they are not accurate enough to use for the general population. Instead, they are typically used in families with a previously affected child. e.g each of two prospective parents carries one cystic fibrosis gene. a. find the probability that their child would have cystic fibrosis. b. find the porbability that ...
