At a coffee shop, the first 100 customers'orders were as follows.Small MediumLargeHot54822Cold8125What is the probability that a customer ordereda small given that he or she ordered a colddrink?Rounded to the nearest percent, [? ]%

Answer 1

Divide the total amount of customers that ordered a small cold over the number of customers that ordered a cold to find the requested probability.

The total amount of people that ordered a cold coffee, is:

`8+12+5=25`

Since 8 customers ordered a small cold coffee, then the probability is:

`(8)/(25)`

Write the probability as a percent:

`(8)/(25)\cdot100\text{ \%}=32\text{ \%}`

Therefore, the answer is:

`32\text{ \%}`
