Consider the experiment of drawing two cards without replacement from an ordinary deck of 52 playing cards.
#1. What are the odds in favor of drawing a spade and a heart?
What are the odds in favor of getting at least one head in three successive flips of a coin?
The odds of drawing a spade are 13/52, then drawing the heart would be 13/51. To find the probability of getting both, multiply the individual probabilities.
Below are the possible outcomes of the tosses.
"At least one head" can be rephrased as 1, 2, or 3 heads. How many of the 8 possibilities fit?
