Conditional Probability

Let A and B be two events associated with a random

experiment. Then, the probability of occurrence of event A

under the condition that B has already occurred and

P (B) $\neq$ 0, is called the conditional probability and it is denoted

by P (A/B). Thus, we have

P (A/B) = Probability of occurence of A given that B has

already occurred.

A doctor is called to see a sick child. The doctor has prior information that 80% of sick children in that area have the flu, while the other 20% are sick with measles. Assume that there is no other disease in that area. A well-known symptom of measles is a rash. From the past records it is known that, chances of having rashes given that sick child is suffering from measles is 0.95. However, occasionally children with flu also develop rash, whose chances are 0.08. Upon examining the child, the doctor finds a rash. What is the probability that the child has measles?
