Answer :
Amount of kings in a standard deck of 52 cards: 4
Amount of queens in a standard deck of 52 cards: 4
Probability of drawing a king on the first draw:
4/52, or simplified 1/13
Probability of drawing a queen on the 2nd draw:
4/51
Amount of queens in a standard deck of 52 cards: 4
Probability of drawing a king on the first draw:
4/52, or simplified 1/13
Probability of drawing a queen on the 2nd draw:
4/51
there are 4 kings in a deck
4/52 = 1/13 chance
one card has been removed, four queens in a deck
4/51 can't be simplified = 4/51 chance
4/52 = 1/13 chance
one card has been removed, four queens in a deck
4/51 can't be simplified = 4/51 chance
