To calculate the probability that the next person will purchase one or more costumes, we need to consider the total number of visitors and the number of visitors who purchased at least one costume.
The total number of visitors is the sum of the number of visitors who purchased exactly one costume and the number of visitors who purchased more than one costume:
288 visitors + 13 visitors = 301 visitors
Now, we calculate the probability by dividing the number of visitors who purchased at least one costume by the total number of visitors:
(288 + 13) / (95 + 288 + 13) = 301 / 396 ≈ 0.76
Therefore, the probability that the next person will purchase one or more costumes is approximately 0.76 when rounded to the nearest hundredth.
In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Khloe sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 95 visitors purchased no costume. 288 visitors purchased exactly one costume. 13 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase one or more costumes as a decimal to the nearest hundredth.
