Answer: There are 64 relations from A to B.
Step-by-step explanation:
Number of relation from set A to B = [tex]2^{\text{ (Number of eklemnts in A x B)}}[/tex]
[tex]=2^{\text{(Number of elements in set A ) x (Number of elements in set B)}}[/tex]
Since, A={Φ,{Φ},{Φ,{Φ}}} and B={1,2}
i.e. Number of elements in set A = 3
Number of elements in set B = 2
So, Number of relation from set A to B = [tex]2^{3\times 2}[/tex]
[tex]= 2^6= 64[/tex]
Hence, there are 64 relations from A to B.
