You have two sets A and B defined as follows:
[tex]\begin{gathered} A=\mleft\lbrace1,2,3,4,5\mright\rbrace \\ B=\mleft\lbrace6,7,8,9\mright\rbrace \end{gathered}[/tex]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
