Question

If A={1,2,3} , B={a,b,c} Then number of functions from a to b are .....

Answer 1

Hey there !

Given ,

A={1,2,3} => n(A) =3

B={a,b,c} => n(B)=3


We know that number of possible functions from A to B are n(B)^n(A)

=3^3

=27
Hence ,possible number of functions from A to B are 27

Answer 2

Answer:

If A={1,2,3}, B={x,y} , then the number of functions that can be defined from A into B is 12 b.
