Expert Answer
P(A U B) = P(A) + P(B) - P(A ∩ B)
P(A) = Probabiltiy that number greater than 3 (4, 5, 6) is obtained = 3/6
P(B) = Probability that number less than 5 (1,2,3,4) is obtained = 4/6
P(A ∩ B) = Probability that number greater than 3 and less than 5 (4) is obtained = 1/6
Thus P(A U B) = 3/6 + 4/6 - 1/6 = 1
