What is the probability of two mutually exclusive events?

Two events are mutually exclusive if they cannot occur at the same time

A deck of cards has 52 cards

What is the probability that a card is either a queen or a jack? Note word OR for mutually exclusive events, , We simply add here

The probability of a King or jack is 4/52 or 1/13,

When we combine these two Events:

The probability of a King or a Jack is (1/13) + (1/13) = 2/13

P(A or B) = P(A) + P(B)
