Answer 2

Step-by-step explanation:

Given, n (A) = 5 and n (B) = 7

Given, n (A) = 5 and n (B) = 7 We know that, if n (A) = P and n (B) = q,

Given, n (A) = 5 and n (B) = 7 We know that, if n (A) = P and n (B) = q, then number of functions from A to

$q^p$

.

. ∴ Number of function from A to B =

$7^5$
