Question

Let A={1,2,3,4,5} and B={6,7,8,9}. Find AnB. Write your answer in proper set notation. If the answer is the empty set, put 0/

Answer 1

Answer: ∅ or empty set

Step-by-step explanation: Since there are no common elements between A and B, the intersection is the empty set ∅

Answer 2

You have two sets A and B defined as follows:

`\begin{gathered} A=\mleft\lbrace1,2,3,4,5\mright\rbrace \\ B=\mleft\lbrace6,7,8,9\mright\rbrace \end{gathered}`

You have to find A∩B, this notation indicates that you have to determine the intersection between both sets. The intersection between two sets includes the
