needed detailed solution and clearedexplanation for the question below thank you4. In a certain country region, it is known from past experience that the probability of selecting an adultover 40 years of age with cancer is 0.05. The probability of a doctor correctly diagnosing a person withcancer as having the disease is 0.78 and the probability of incorrectly diagnosing a person withoutcancer as having the disease is 0.06.a) What is the probability that a person diagnosed as having cancer actually has the disease?b) What is the probability that a person diagnosed as not having cancer actually does not have thedisease?c)What can be concluded from the results of (a) and (b)?

A certain disease affects about 1 out of 10, 000 people. There is a test to check whether the person has the disease. The test is quite accurate. In particular, we know that • the probability that the test result is positive (suggesting the person has the disease), given that the person does not have the disease, is only 2 percent; • the probability that the test result is negative (suggesting the person does not have the disease), given that the person has the disease, is only 1 percent. A random person gets tested for the disease and the result comes back positive. What is the probability that the person has the disease?
