The probability that the next person will purchase exactly one costume is 67%.

<h3>How to calculate the probability?</h3>

Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1.

53 visitors purchased no costume.

151 visitors purchased exactly one costume.

22 visitors purchased more than one costume.

Total visitor = 53 + 151 + 22

= 226

Probability that the next person will purchase exactly one costume will be:

= Those with one custome / Total visitors × 100

= 151 / 226 × 100

= 67%

The probability is 67%.
