A student is to take her final exams in two subjects. The probability that she will pass the first subject is 3/4 and the probability that she will pass the second subject is 2/3. What is the probability that she will pass one exam or the other exam?	Choose the most appropriate option: A) 5/12 B) 1/2 C) 7/12 D) 5/7 E) 11/12
Let the two subjects be X (probability of passing 3/4) and Y (probability of passing 2/3)   The probability of passing in X only is 3/4 times 1/3 (failing in Y) = 1/4   The probability of passing in Y only is 2/3 times 1/4 (failing in X) = 1/6   Therefore the total probability = 1/4 + 1/6 = 5/12   Hence 5/12
