Question

caleb performed an experiment in which he rolled a number cube 100 times. he recorded the results in a table. what was the experimental probability of rolling a 4?
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

Explanation:

Step1: Recall experimental - probability formula

Experimental probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$

Step2: Identify values

The number of times 4 was rolled (favorable outcomes) is 14, and the total number of rolls (total outcomes) is 100.

Step3: Calculate probability

Experimental probability of rolling a 4 = $\frac{14}{100}=0.14$

Answer:

0.14
