WebbOption A) Is Impossible. If E and F are mutually exclusive events then p ( E ∪ F) = p ( E) + p ( F) p ( E ∪ F) = 0.3 + 0.8 = 1.1. Here, p ( E ∪ F) > 1 which is a contradiction to the axiom. ∴ E and F cannot be mutually exclusive events. Option B) Is possible. Events F and G can be mutually exclusive events. Webb18 juli 2024 · Find the probability that the card is a club or a face card. Solution. There are 13 cards that are clubs, 12 face cards (J, Q, K in each suit) and 3 face cards that are clubs. P(club or face card) = P(club) + P(face card) − P(club and face card) = 13 52 + 12 52 − 3 52 = 22 52 = 11 26 ≈ 0.423. The probability that the card is a club or a ... isc pathway
