Title: Mutually Exclusive and Overlapping Events
Objective(s)
Today I will:
● 9.4: Apply the General Addition Rule for probability
and interpret the answers in terms of the model.
I will know I’ve got it when I can:
● Determine the probability of mutually exclusive events.
● Determine the probability of overlapping events.
#1: A dodecahedron (12-sided die) has 12 sides numbered 1 through 12. The die is rolled and the number
is recorded. Event A is rolling an even number. Event B is rolling a 7. What is the probability of rolling an
even number or a 7?
#2: A dodecahedron (12-sided die) has 12 sides numbered 1 through 12. The die is rolled and the number is
recorded. Event A is rolling an even number. Event B is rolling a number greater than 7. What is the
probability of rolling an even number or a number greater than 7?

Term Definition Example
Mutually
Exclusive
Events
Two events that do not have any
outcomes in common
P(A or B) = P(A) + P(B)
