Question

Caleb performed an experiment in which he rolled a number cube 100 times. He recorded the results in a table.

Answer 1

Answer:

The experimental probability of rolling a 4 is 0.14.

Step-by-step explanation:

Given : Caleb performed an experiment in which he rolled a number cube 100 times. He recorded the results in a table.

Number Rolled - Frequency - Experimental Probability

1                                 15                    0.15

2                                17                     0.17

3                                17                     0.17

4                                14                      ?

5                                21                     0.21

6                                16                     0.16

To find : What was the experimental probability of rolling a 4?

Solution :

Formula to find the experimental probability is

$\text{Experimental Probability}=\frac{\text{Frequency of the number}}{\text{Total number of times cube roll}}$

We also notice that this pattern follows by other numbers also.

So, The experimental probability of rolling a 4 is

$\text{Experimental Probability}=\frac{14}{100}$

$\text{Experimental Probability}=0.14$

Therefore, The experimental probability of rolling a 4 is 0.14.

Answer 2

Answer: The experimental probability of rolling a 4 is 0.14

Experimental probability of rolling a 4 = (frequency of rolling a 4) / (Total number of rolling the number cube)

Frequency of rolling a 4 = 14
Total number of rolling the number cube = 100

Replacing in the formula above:
Experimental probability of rolling a 4 = 14 / 100
Experimental probability of rolling a 4 = 0.14
