I am trying to work out but am having no luck with the following.

It two players have 5 cards each from which they can choose. The cards are marked Legs, Body, Head, L Arm, Right arm

What are the odds of the picking player choosing a card the other does not pick if they are picking
Second Player 1 card 2 cards 3 cards 4 cards 5 cards
First Player
1 card 0%
2 cards
3 cards
4 cards
5 cards 100% 100% 100% 100% 100%

Its for a game and i am trying to work out the odds. If the player picking first is attacking there need to pick a cards that the second player doesnt and its the odds of that that i'm looking for.

Thank you

You are thinking about probability, not odds.

Please be a bit more specific. How many cards is the first player drawing? Are they drawing the same number of cards? I'll call the cards {1,2,3,4,5}. If they both draw two cards and the first player draws {1,3} and the second draws {3,4}, does that count? More detail please.
