Two cards are drawn from a standard deck without replacement. Find each probability and state your answers as simplified fractions. What is the probability that the first card is a spade? Where should this value be placed on the tree diagram below? What is the probability that the second card is a spade, given that the first was a spade? Where should this value be placed on the tree diagram below? What is the probability that the first and second cards are both spades? Where should this value be placed on the tree diagram below?
