I️n every 52 deck of cards there are 4 different faces: clubs, clovers, diamonds, and hearts.
Each face has 13 cards, of those 13 cards there is an A, 2-10, and a king, queen, and jack
Because there is only one jack of diamonds the probability of getting I️t from a 52-card deck is 1/52 or .019 or 1.9% chance of getting I️t
