Question
At a coffee shop, the first 100 customers' orders were as follows:

|        | Small | Medium | Large |
|--------|-------|--------|-------|
| **Hot**  | 5     | 48     | 22    |
| **Cold** | 8     | 12     | 5     |

What is the probability that a customer ordered a cold drink given that he or she ordered a large?

\[ P(\text{Cold} \mid \text{Large}) = [?] \]

Round to the nearest hundredth.

**Explanation:**
The table displays a breakdown of 100 customer orders by size (Small, Medium, Large) and type (Hot, Cold). To find the probability that a customer ordered a cold drink given that it was large, locate the 'Cold' and 'Large' intersection and divide it by the total number of 'Large' orders.
