Look at the illustration below:
Mutually Exclusive Events
B
P(A or B) = P(A) + P(B)
In this illustration it shows that mutually exclusive events are those events which do
not have anything in common. In other words, these events do not have an intersection.
These are characterized by the word "or". It is the sum of individual probability written as,
P(A or B) = P(A) + P(B)
P(A U B) = P(A) + P(B)
Examples:
1. Turning left and right (you cannot do this both at the same time.
2. Getting a head and tail in tossing a coin (you can't do this both at the same
time.
PERFORMANCE TASK 7
Tell whether the following event is a mutually exclusive or NOT. Write an answer on the
space provided.
1. Moving backwards and forwards.
2. Getting an Ace or a Spade from a deck of cards.
3. Getting a face card or a club from a deck of cards.

What is it?
Let us illustrate the probability of mutually exclusive events.
Examples:
1. The probability of getting an ace or a king from a deck of cards.
The figure illustrates mutually
exclusive events. Aces and Kings
cannot occur at the same time. In
