Probability of Compound Events Worksheet

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 ) 


 

 

 

 

 

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. 


 

  • These worksheets will help your students easily solve compound probability questions, i.e., both inclusive and exclusive events.
