A​ new, simple test has been developed to detect a particular type of cancer. The test must be evaluated before it is put into use. A medical researcher selects a random sample of 1000adults and finds​ (by other​ means) that 3​%have this type of cancer. Each of the1000adults is given the​ test, and it is found that the test indicates cancer in 96%of those who have it and in 1%of those who do not. Based on these​ results, what is the probability of a randomly chosen person having cancer given that the test indicates​ cancer? Of a person having cancer given that the test does not indicate​ cancer?
