Question

Number of possible relations from the set A to set B, where $n\left(A\right)=2,n\left(B\right)=5$ is

• A. 1024.0
• B. 01024
• C. 1024

Answer 1

Answer: (A), (B), (C)

Total number of possible relations from a set $A$ to set $B,$, such that $n\left(A\right)=n\&n\left(B\right)=m$ is $2^{n.m}$

Here $n=2\text{and}m=5$
Hence, total number of relations will be $2^{2\times 5}=2^{10}=1024$
