Question

At a coffee shop, the first 100 customers' orders were as follows. Medium Lange 48 22 What is the probability that a customer ordered a hot drink given that he or she ordered a large? P( Hot | Large) = [ ?) Round to the nearest hundredth​

Answer 1

Answer: 0.81 or 81%

Explanation:

We are looking for the probability that the customer ordered a hot drink if they ordered a large one. This means that our whole is 27, since 22 Hot Large + 5 Cold Large = 27 total large drinks.

To find the probability, we will divide the total number of wanted outcomes by the total number of possible outcomes.

`\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{hot large drink}}{\text{large drink}} =(22)/(27) =0.81\text{ or } 81\%`
