**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. 1/27

B. 9/20

C. 1/60

D. 3/30

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 = 27/60. Then, you simplify and you get: 9/20.
