I ask Joseph to pick any 5 cards out of a deck with no Jokers.

He can inspect then shuffle the deck before picking any five cards. He picks out 5 cards then hands them to me (Jack can't see any of this).

Jack looks at the 4 cards i gave him, and says out loud which card Joseph is holding (suit and number). How?
