Approximately 4% of all cases of tularemia are resistant to strepto-mycin, and 25% of all cases are resistant to gentamycin. Given that atularemia case is resistant to streptomycin, the probability that it willalso be resistant to gentamycin is 90%. (a) What is the probability arandomly selected tularemia patient has a case that is resistant to bothstreptomycin and gentamycin? (b) Are resistance to streptomycin andresistance to gentamycin independent?

A biomedical research company produces 40% of its insulin at a plant in Kansas City, and the remainder is produced at a plant in Jefferson City. Quality control has shown that 0.75% of the insulin produced at the plant in Kansas City is defective, while 0.5% of the insulin produced at the plant in Jefferson City is defective. What is the probability that a randomly chosen unit of insulin came from the plant in Jefferson City given that it is defective?
Apparently, depression significantly increases the risk of developing dementia later in lift (BBC News, July 6, 2010). In a recent study it was reported that 22% of those who had depression went on to develop dementia, compared to only 17% of those who did not have depression. Suppose 10% of all people suffer from depression. What is the probability of a person developing dementia? If a person has developed dementia, what is the probability that the person suffered from depression earlier in life?
