even numbers: 2, 4, 6
odd numbers: 1, 3, 5, 7
probability of selecting odd card on 1 draw: 4/7
selecting two odd numbers: 4/7 * 4/7 =
(the probability for the second draw is also 4/7, because the card from the first draw goes back to the deck to be selected)

As an experiment is literally described in your post,
its only outcome is ONE selected card -- not two.
If you want to ask about two cards, then the post and the experiment description MUST be edited/changed ACCORDINGLY.
As presented, it is not a Math problem on probability.
It is simply a mess of words.
