Probability: Independent and Dependent Events
There are 150 people at a play. Ninety are women, and 60 are men. Half are sitting in the lower level, and half are sitting in the upper level. There are 35 women sitting in the upper level. A person is selected at random for a prize. What is the probability that the person is sitting in the lower level, given that the person is a woman? Is the event "person is sitting in the low'er level woman"? Explain. Medicine Suppose that strep throat affects 2% of the population and a test to detect it produces an accurate result 99% of the time. Complete the table. What is the probability that someone who tests positive actually has strep throat?
