Given the following set of cars
[tex]\begin{gathered} T\Rightarrow T\text{oyota} \\ S\Rightarrow\text{SUV} \\ F\Rightarrow\text{Ford} \end{gathered}[/tex][tex]\begin{gathered} n(F)=17 \\ n(\text{S }\cap\text{ T)}\Rightarrow9 \\ n(S\cap T^{\prime})=23-9=14 \\ n(S^{\prime}\cap T^{})=14-9=5 \end{gathered}[/tex]The universal set is the sum of all the subsets given above
[tex]\begin{gathered} n(U)=n(F)+n(\text{S }\cap\text{ T)}+n(S\cap T^{\prime})+n(S^{\prime}\cap T^{}) \\ n(U)=17+9+14+5=45_{} \end{gathered}[/tex]The Venn diagram is show below
