(type a whole number.)
Answer
Explanation:
Step1: Define sets
Let $A$ be the set of houses with a finished basement and $B$ be the set of houses with a three - car garage. We know $n(A) = 49$, $n(B)=52$, $n(A\cap B)=37$ and the total number of houses $n = 79$.
Step2: Calculate number for part b
To find the number of houses with a three - car garage but not a finished basement, we use the formula $n(B\cap\overline{A})=n(B)-n(A\cap B)$. Substitute the known values: $n(B) = 52$ and $n(A\cap B)=37$. So $n(B\cap\overline{A})=52 - 37$. $52-37 = 15$
Answer:
15
