A randomly chosen group is tested for a disease. Within this group, each individual has a probability of 0.1 of having the disease. A test is performed to identify the individuals with the disease. The test has two outcomes: positive or negative. If the individual does not have the disease, the test outcome is “negative” 90 percent of the time. If the individual has the disease, the test outcome is “negative” 20 percent of the time. Individuals who test “positive” are sent to a hospital for further treatment. What is the probability that an individual sent to the hospital indeed has the disease? pls help me with this.
