**Finding experimental probability worksheets :**

Worksheet on finding experimental probability is much useful to the students who would like to practice solving real-world problems on probability.

The formula given below can be used to find experimental probability.

1. David tossed a coin 20 times and received head 12 times and tail 8 times. Find the experimental probability of getting tail.

2. A six faced cube numbered from 1 to 6 is rolled 5 times and 3 is received twice and 5 is received thrice. Find the experimental probability of getting the number 3.

3. A dentist has 400 male and female patients that range in ages from 10 years old to 50 years old and up as shown in the table. What is the experimental probability that the next patient will be female and in the age range 22–39 ?

**Problem 1 : **

David tossed a coin 20 times and received head 12 times and tail 8 times. Find the experimental probability of getting tail.

**Solution : **

**Step 1 : **

Find the total no. of trials.

Total number of trials = 20

**Step 2 : **

Find the no. of times tail received.

Number of times tail received = 8

**Step 3 : **

Find the probability.

Experimental probability = 8/20

Simplify.

Experimental probability = 2/5

**Problem 2 : **

A six faced cube numbered from 1 to 6 is rolled 5 times and 3 is received twice and 5 is received thrice. Find the experimental probability of getting the number 3.

**Solution : **

**Step 1 : **

Find the total no. of trials.

Total number of trials = 5

**Step 2 : **

Find the no. of times 3 received.

Number of times 3 received = 2

**Step 3 : **

Find the probability.

Experimental probability = 2/5

**Problem 3 : **

A dentist has 400 male and female patients that range in ages from 10 years old to 50 years old and up as shown in the table. What is the experimental probability that the next patient will be female and in the age range 22–39 ?

**Solution : **

**Step 1 : **

Find the total no. of patients.

Total no. of patients is

= 44 + 66 + 32 + 53 + 36 + 50 + 45 + 74

= 400

**Step 2 : **

Find the no. of female patients in the age range 22 - 39.

No. of female patients in the age range 22 - 39 = 50

**Step 3 : **

Find the probability.

Experimental probability = 50/400

Simplify.

Experimental probability = 1/8
