The probability of two or more independent events happening together is compound probability. It is the likelihood of two or more events occurring together. An independent event is a type of event that is not affected by the other events taking place simultaneously. The result of a compound probability will always lie between 0 and 1.

Firstly, determine if the event is mutually inclusive or exclusive.

Then, you may use the formula accordingly.

Remember, the result will always lie between 0 and 1.

Here is an example of solving a problem on compound probability. Let’s look at the given example below to understand compound probability.

Compound Probability Formula = P(A or B) = P(A) + P(B) ( Exclusive Events )

= P(A or B) = P(A) + P(B) - P ( A and B ). ( Inclusive Events )

Q. If a dice is rolled, find the compound probability that either a 2 or 3 will be obtained.

Answer: P ( 3 ) = ⅙

P ( 2 ) = ⅙

This is an example of a mutually exclusive event.

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

P ( 2 or 3 ) = ⅙ + ⅙

So, P ( 2 or 3 ) = ⅓.

Why should you use a Compound Probability worksheet for your students?

The compound probability worksheet will help your students to be well-versed with the concept of probability.
