Few Questions • Were the people who were cut really worse at flipping coins? • What would happen if we let each athlete flip the coin a thousand times? Let’s say a player’s ABILITY to flip a coin and it landing on heads is 60%. • If the player flips the coin10 times, would it be unreasonable for her to land on heads only 3 times? • How about all 10 flips?
