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 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 15 Â Â Â Â Â Â Â Â Â Â 0.15
2 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 17 Â Â Â Â Â Â Â Â Â Â 0.17
3 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 17 Â Â Â Â Â Â Â Â Â Â 0.17
4 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 14 Â Â Â Â Â Â Â Â Â Â Â ?
5 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 21 Â Â Â Â Â Â Â Â Â Â 0.21
6 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 16 Â Â Â Â Â Â Â Â Â Â 0.16
To find : What was the experimental probability of rolling a 4?
Solution :
Formula to find the experimental probability is
[tex]\text{Experimental Probability}=\frac{\text{Frequency of the number}}{\text{Total number of times cube roll}}[/tex]
We also notice that this pattern follows by other numbers also.
So, The experimental probability of rolling a 4 is
[tex]\text{Experimental Probability}=\frac{14}{100}[/tex]
[tex]\text{Experimental Probability}=0.14[/tex]
Therefore, The experimental probability of rolling a 4 is 0.14.
