Vedclass · Answer

(B) Two sets are said to be equivalent if they have the same number of elements,i.e.,their cardinal numbers are equal.In option $A$: $n(A) = 4$ and $n(B) = 4$. Since $n(A) = n(B)$,they are equivalent.In option $B$: $n(A) = 3$ and $n(B) = 4$. Since $n(A) 
eq n(B)$,they are not equivalent.In option $C$: $n(A) = 0$ and $n(B) = 0$. Since $n(A) = n(B)$,they are equivalent.In option $D$: $n(A) = 3$ and $n(B) = 3$. Since $n(A) = n(B)$,they are equivalent.Therefore,the pair in option $B$ is not equivalent.

Which of the following pairs of sets are not equivalent?
