Answer :
The experimental probability of Jill rolling a specific outcome on a dice can be calculated by dividing the number of times the outcome occurred (5) by the total number of rolls (20).
Therefore, the experimental probability is 5/20, which can be simplified to 1/4 or 0.25.
To determine the experimental probability, we look at the number of successful outcomes (in this case, rolling the desired outcome) and divide it by the total number of trials (dice rolls).
In this situation, Jill rolled the desired outcome 5 times out of 20 rolls. So, the experimental probability is given by 5/20. To simplify this fraction, we can divide both the numerator and denominator by their greatest common factor, which is 5 in this case.
Dividing 5 by 5 gives 1, and dividing 20 by 5 gives 4. Therefore, the experimental probability is 1/4 or 0.25.
Hence, the experimental probability of Jill rolling a specific outcome on a dice, based on the given data, is 1/4 or 0.25.
