Do you understand what a one-to-one correspondence is now?
Yes, I do! Thank you!
A one-to-one correspondence is when two sets, A and B, can be paired together so that for one element of A there is exactly one element of B. Also for each one element of B there is exactly one element of A. If these two are true then these are in one-to-one correspondence.
