Probability of Compound Events Worksheet

7 problems

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.

Teaching Compound Probability Easily 


  • 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 )
