Question

Choose the number that is the intersection of sets A and B.

Answer 1

ANSWER:

$A\operatorname{\cap}B=\lbrace5\rbrace$

STEP-BY-STEP EXPLANATION:

We have the following sets:

$\begin{gathered} A={}{}{}\lbrace5,10,15,20,25,30...\rbrace \\ \\ B=\lbrace1,3,5,7,9,11,13\rbrace \end{gathered}$

We must find the intersection of these groups, taking into account that the numbers in common between both sets, then we would have:

$\begin{gathered} A\cap B=\lbrace5\rbrace \\ \end{gathered}$

So the correct answer is the first option
