Question

Find the intersection of $A$ and $B$ using venn diagram.

• A. $\left\{1,3,5,7\right\}$
• B. $\left\{5,7\right\}$
• C. $\left\{1,2,3,5,7,10\right\}$
• D. None of these.

Answer 1

The correct option is B

$\left\{5,7\right\}$

Find the intersection.

We know that, if two sets $A$ $B$ are given, then the intersection of $A$ and $B$ is the subset of the universal set$\mathrm{U}$, which consists of elements common to both $A$ and$B$. It is denoted by the symbol$‘\cap ’$.

So, from the given Venn diagram we can say that the intersection of $A$ and $B$or $A\cap B$ is$\left\{5,7\right\}$.

Hence, the intersection of $A$ and $B$ is$\left\{5,7\right\}$, so, the correct answer is an option (B).
