Accepted Solution

A:
Solution: Craig chooses a ball from a bag with red, green and yellow balls. He marks the ball and then replaces it. He then chooses a second ball. By replacing the ball, Craig creates circumstances that are identical for each event. Marking the ball does not affect the results.
