Compare Probabilities Worksheet

8 problems

The likelihood of an event occurring is known as probability. The ratio to the number of favorable outcomes with respect to the total number of outcomes is probability. The number of favorable outcomes is denoted by ‘x,’ whereas the number of outcomes is denoted by ‘x.’ The formula to find probability is; 


 

The Probability of an event = Favorable Outcomes / Total Outcomes = x/n.


 

There are certain things to remember while comparing the probabilities of two events.

Teaching Comparing Probability Easily 

 

  • Firstly, try to determine the probability of the first event. 


 

  • Secondly, identify the probability of the second event. 


 

  • Lastly, compare both the answers to know which has the higher probability. 



 

Here is an example of solving a problem by comparing probabilities. Let’s look at the given example below to understand more about comparing probabilities. 


 

Q. Suppose there are two horses. The first horse runs 100 races and wins 50. Likewise, the second horse runs 100 races and wins 80. Compare the probability between the two. 


 

Step 1: Find the Probability of the first event. 


 

The probability of winning is = 50 /100 = 0.50 or 50 percent.
