Lesson: Mutually Exclusive Events Mathematics

In this lesson, we will learn how to identify mutually exclusive events and find their probabilities.

Lesson Plan

Students will be able to

understand what mutually exclusive events are and determine if two or more events are mutually exclusive,
know that the probability of two mutually exclusive events occurring at the same time is zero and therefore know subsequent probability rules involving mutually exclusive events:
- ,
- ,
- ,
use facts about mutually exclusive events to solve probability problems.

Q1:

In each case, decide whether the two events are mutually exclusive or not.

Event : Rolling a 6-sided die and getting a number greater than 4.

Event : Rolling a 6-sided die and getting an odd number.

Event : Rolling an 8-sided die and getting a number less than 4.

Event : Rolling an 8-sided die and getting a number greater than 4.

Event : Rolling a 20-sided die and getting a prime number greater than 3.

Event : Rolling a 20-sided die and getting a factor of 15.

Q2:

If a die is rolled once, then what is the probability of getting an odd and an even number together?

Q3:

If and are two mutually exclusive events from a sample space of a random experiment, find .
