Two cards are drawn without replacement from an ordinary
deck of 52 playing cards. What is the probability that
both are spades if the first card drawn was a spade?
*Did I do this right?
. 52 cards. 13 are spades. 1 picked is already a spade. That leaves 12 spades in the deck.
After picking the first card, there are 51 cards left in the deck (without replacement), and there are 12 spades.
