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? table columns: number (1,2,3,4,5,6), frequency (15,17,17,14,21,16), experimental probability (0.15, 0.17, 0.17, ?, 0.21, 0.16)

Explanation:

Step1: Recall experimental probability formula

Experimental probability of an event is given by the number of times the event occurs divided by the total number of trials. The formula is $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of trials}}$.

Step2: Identify values for rolling a 4

For rolling a 4, the number of favorable outcomes (frequency) is 14, and the total number of trials (rolls) is 100.

Step3: Calculate the probability

Using the formula, we have $P = \frac{14}{100}= 0.14$.

Answer:

0.14
