To find the probability that someone prefers salad given that they prefer sweet tea, we can use the formula for conditional probability:
\[ P(A | B) = \frac{P(A \cap B)}{P(B)} \]
Where:
- \( A \) is the event of preferring salad.
- \( B \) is the event of preferring sweet tea.
From the table:
- The total number of people who prefer sweet tea is 61.
- The number of people who prefer both salad and sweet tea is 32.
Now we can substitute these values into the conditional probability formula:
\[ P(\text{Salad} | \text{Sweet Tea}) = \frac{P(\text{Salad} \cap \text{Sweet Tea})}{P(\text{Sweet Tea})} = \frac{32}{61} \]
Thus, the probability that someone prefers salad given that they prefer sweet tea is:
\[ \frac{32}{61} \]
This fraction is already in its reduced form. Therefore, the final answer is:
\[ \boxed{\frac{32}{61}} \]
