To find the probability of the next visitor purchasing no costume, we divide the number of visitors who didn't purchase (71) by the total number of visitors (219), which gives us a probability of 0.32 when rounded to the nearest hundredth.
The question pertains to the probability that the next person who visits a website will purchase no costume.
To calculate this, we need to understand the relative frequency of this event, based on historical data, and express it as a decimal.
According to the data provided:
71 visitors purchased no costume.
139 visitors purchased exactly one costume.
9 visitors purchased more than one costume.
To find the probability that the next person will purchase no costume, we divide the number of visitors who purchased no costume by the total number of visitors:
Probability = Number of visitors who purchased no costume / Total number of visitors
Probability = 71 / (71 + 139 + 9)
Probability = 71 / 219
Probability = 0.3242 (rounded to the nearest hundredth)
Thus, the probability that the next person will purchase no costume is 0.32.
