Given $A=\{11,13,15,17,19\}$ and $B=\{10,11,12,13,14,15\}$, find the intersection of set $A$ and set $B$. (Enter your answer in roster notation.)
$A \cap B=$
Answer
Final Answer: $A \cap B = \boxed{\{11, 13, 15\}}$
Step 1 ：Given sets $A=\{11,13,15,17,19\}$ and $B=\{10,11,12,13,14,15\}$, we are asked to find the intersection of set $A$ and set $B$. The intersection of two sets is the set of elements that are common to both sets.
Step 2 ：So, we need to find the elements that are present in both set $A$ and set $B$.
Step 3 ：Comparing the elements of set $A$ and set $B$, we find that the common elements are $11$, $13$, and $15$.
Step 4 ：Therefore, the intersection of set $A$ and set $B$ is $\{11, 13, 15\}$.
Step 5 ：Final Answer: $A \cap B = \boxed{\{11, 13, 15\}}$
