Answer:
74.71%
Explanation:
To calculate the experimental probability of the next scoop that they sell being vanilla, we need to divide the amount of scoops of ice cream that were vanilla (65 scoops) by the total amount of scoops of ice cream sold (87 scoops):
Probability of next scoop being vanilla = 65 / 87 = 0.7471 = 74.71%
The experimental probability of the next scoop they sell being vanilla is 74.71%.
