submit answer
Step1: Calculate the total number of visitors
The total number of visitors is the sum of those who purchased no costume, exactly one costume, and more than one costume.
$187 + 228+29=\frac{187 + 228+29}{1}=444$
Step2: Calculate the number of visitors who purchased no more than one costume
The number of visitors who purchased no more than one costume is the sum of those who purchased no costume and exactly one costume.
$187 + 228=\frac{187 + 228}{1}=415$
Step3: Calculate the probability
The probability formula is $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$.
$P=\frac{415}{444}\approx0.9347$
Step4: Convert to percentage
To convert the decimal to a percentage, multiply by 100.
$0.9347\times100 = 93.47\%$
