Question

From the sets given below, pair the equivalent sets:

$A=\{1,2,3\}$,

$B=\{t,p,q,r,s\}$,

$C=\{a,\beta ,\gamma \}$,

$D=\{a,e,i,o,u\}$

Answer 1

We know that,

Sets, which are having same number of elements

are called equivalent sets. So,

For $A=\{1,2,3\}$

Number of elements in set $A=3$

For $B=\{t,p,q,r,s\}$

Number of elements in set $B=5$

For $C=\{a,\beta ,\gamma \}$

Number of elements in set $C=3$

For $D=\{a,e,i,o,u\}$

Number of elements in set $D=5$

Hence, set $A$ is equivalent to set $C$

And set $B$ is equivalent to set $D$.
