The formula to find the number of elements in $A \cap B$ is given by $n(A) + n(B) - n(A \cup B)$. Substituting the given values, we get $37 + 52 - 70 = 19$.

Solve the Problem If n(A)=37,n(B)=52, and n(A∪B)=70, find n(A∩B)\text { If } n ( A ) = 37 , n ( B ) = 52 \text {, and } n ( A \cup B ) = 70 \text {, find } n ( A \cap B ) If n(A)=37,n(B)=52, and n(A∪B)=70, find n(A∩B)

Solve the Problem $\text { If } n ( A ) = 37 , n ( B ) = 52 \text {, and } n ( A \cup B ) = 70 \text {, find } n ( A \cap B )$
