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 oe more costumes as a decimal to the nearest hundredth

Answer 1

First, we need to find the total number of visitors:

Total visitors = 95 + 288 + 13 = 396

Next, we need to find the number of visitors who purchased one or more costume:

P(one or more costume) = (288 + 13) / 396 = 301 / 396

To express this probability as a decimal to the nearest hundredth, we can divide 301 by 396 and round to the nearest hundredth:

P(one or more costume) ≈ 0.76

Therefore, the probability that the next person will purchase one or more costumes is approximately 0.76, or 76% to the nearest hundredth.
