Suppose we have a sample space S and two events A and B such that S= AUB and An B= Ø and an event E, Suppose we have the following results: • P(A) = 1/3 P(B) = 2/3 P(E|A) = 1/2 P(E|B) = 1/4 What is P(E) ? Write your answer as a single fraction of integers. For example, if the answer were 17/20 then enter 17/20 with no spaces or other symbols. You may reduce the fraction by cancelling factors common to the numerator and denominator but you do not need to do this.
