Answer
Explanation:
Step1: Identify number of small - coffees
The number of small - coffees is 7.
Step2: Calculate probability of small and coffee
The total number of drinks is 33. The probability of a drink being a small and coffee is the number of small - coffees divided by the total number of drinks. So $P(\text{small and coffee})=\frac{7}{33}$.
Answer:
$\frac{7}{33}$
