171 visitors purchased no costume.
148 visitors purchased exactly one costume.
34 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase more than one costume as a fraction in simplest form.
We can use the number of visitors who purchased more than one costume and the total number of visitors who purchased costumes to find the probability:
Probability = number of visitors who purchased more than one costume / total number of visitors who purchased costumes
Total number of visitors who purchased costumes = 148 + 34 = 182
Probability = 34/182
Simplify the fraction by dividing both the numerator and denominator by 2:
Probability = 17/91
Therefore, the probability that the next person will purchase more than one costume is 17/91.
