Question
A six-sided die is rolled ( 10 ) (10) times, and the results are listed below.
3 3 , 4 4 , 1 1 , 1 1 , 2 2 , 6 6 , 6 6 , 5 5 , 6 6 , 3 3
What is the experimental probability of rolling a ( 3 ) (3) ?
Solution
The experimental probability of an event is calculated by dividing the number of times the event occurred by the total number of trials.
In this case, the event is rolling a 3, and the total number of trials is 10 (since the die was rolled 10 times).
Looking at the results, we can see that a 3 was rolled 3 times.
So, the experimental probability of rolling a 3 is 3 (the number of times a 3 was rolled) divided by 10 (the total number of rolls), which equals 0.3 or 30%.
