Given a function `f:AtoB,` where `A={1,2,3,4,5}` and `B={6,7,8}`
Find number of all such functions `y=f(x)` which are one-one?

Consider the function f:A rarr A where A:{1,2,3,4,5} which satisfy the condition f(f(x))=x, If the number of such functions are lambda, then

Consider the function f: A -> A where A:{1,2,3,4,5} which satisfy the condition f(f(x))=x, If the number of such functions are lambda, then

If X={1,2,3,4,5} and Y={a,b,c,d,e,f} and f:X rarr Y , find the total number of functions .

A function f: A to B where A ={a,b,c} , B={1,2,3,4} , How many function can be defined from A to B which are not one-one such that 2 belong f(A)

If A= {1,3,5,7} and B= {1,2,3,4,5,6,7,8} , then the number of one-to-one functions from A into B is

The number of one-one functions from A to B where A=(1, 2, 3, 4) and B=(1, 2 ,3 ,4 ,5 ,6) such that f(i)!=i is

The number of one-one functions from A to B where A= {1, 2, 3, 4} and B={1, 2, 3, 4, 5, 6} such that f(i)!=i for any i is

If A = {1,3,5,7} and B = {1,2,3,4,5,6,7,8}, then the number of one-to-one functions from A into B is

Let A={1,2,3,4} , B={1,2,3,4,5,6,7,8} the number of one - one functions f: A rarr B such that f(i)!=i , for i=1,2,3,4
