Question

n(A) = m, n(B) = n. The total number of non empty relation from A to B is ..........

(A) mn (B) 2mn (C) 2mn – 1 (D) 2mn​

Answer 1

Answer:

2^mn -1

Step-by-step explanation:

n(A) = m

n(B) = n

》Total number of relations from a set A to set B = 2^mn

(this includes 1 empty relation)

therefore,

Total number of non empty relation from

set A to set B = 2^mn -1

So, option (C) is correct.
