WebbEvent A is drawing a King first, and Event B is drawing a King second. For the first card the chance of drawing a King is 4 out of 52 (there are 4 Kings in a deck of 52 cards): P (A) = 4/52 But after removing a King from the deck the probability of the 2nd card drawn is less likely to be a King (only 3 of the 51 cards left are Kings): Webb1 aug. 2024 · Given the events A and B : P ( A U B) = P ( A) + P ( B) - P ( A ∩ B ). Here we account for the possibility of double-counting those elements that are in both A and B, and that is why we subtract the probability of the intersection. The question that arises from this is, “Why stop with two sets?
