Experimental Probability

Definition of Experimental Probability

  • Experimental probability of an event is the ratio of the number of times the event occurs to the total number of trials.
     

Examples of Experimental Probability

  • Sam rolled a number cube 50 times. A 3 appeared 10 times.

Then the experimental probability of rolling a 3 is 10 out of 50 or 20%.

Solved Example on Experimental Probability

A coin is tossed 60 times. 27 times head appeared. Find the experimental probability of getting heads.

Choices:

A.

B.

C.

D.

Correct Answer: B

Solution:

Step 1: Experimental probability = number of times the event occurs / total number of trials.

Step 2: Number of times heads appeared = 27.                         

Step 3: Total number of experiments = 60.

Step 4: So, experimental probability of getting a head =  = .
