WebP(E ∪ F) = P(E) + P(F) Notice that with mutually exclusive events, the intersection of E and F is the empty set. The probability of spinning an orange is 3 6 = 1 2 and the probability of spinning a d is 1 6. We can find the probability of spinning an orange or a d simply by adding the two probabilities. P(E ∪ F) = P(E) + P(F) = 1 2 + 1 6 = 2 3.
