- 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 =
= .
