If the events A and B are not mutually exclusive, the probability of getting A or B that is P (A ∪ B) formula is given as follows:
P (A ∪ B) = P(A) + P(B) – P (A and B)

I didn't use P (A ∪ B) = P(A) + P(B) – P (A and B).

Do you have two mutually exclusive word problems for me?

two mutually exclusive word problems

1. One card is drawn from a well-shuffled deck of 52 cards. What is the probability of getting a king or an ace?
2. A bag contains 8 black pens and 2 red pens and if a pen is drawn at random. What is the probability that it is black pen or red pen?
