(type a whole number.)
Step1: Recall the principle of inclusion - exclusion
The formula for $|A\cup B|=|A| + |B|-|A\cap B|$, where $A$ is the set of houses with a finished basement and $B$ is the set of houses with a three - car garage.
Step2: Identify the given values
We know that $|A| = 49$, $|B|=52$, and $|A\cap B| = 37$.
Step3: Calculate $|A\cup B|$
Substitute the values into the formula: $|A\cup B|=49 + 52-37$.
$|A\cup B|=64$.
