If n(a)=4, n(B)=2. Find the total number of relation that exists between A and B

Step-by-step explanation:

Given that,

n(A) = 4

n(B) = 2

We know that

The total number of relations from A to B if n(A) = m and n(B) = n is 2^mn

We have m = 4 and n = 2

Total number of relations = 2^(4×2)

⇛ 2⁸

⇛256

Hope this helps!
