In the Game of Roulette, a Wheel Spins and a Ball

In the game of roulette, a wheel spins and a ball lands at random in one of an equal number of black and red slots. Because the ball landed in a red slot four times in a row, Cal believes it will land in a black slot on the next spin. Which MOST accurately describes the validity of Cal's belief?

A) Cal is most likely correct because the law of averages should apply.
B) Cal is most likely correct because the probability of a ball landing in a red slot increases for any spin that immediately follows a black outcome.
C) Cal is incorrect in believing that random outcomes alternate more than they really do.
D) Cal is incorrect because the ball would need to land in the red slot several more times in a row before increasing its likelihood of landing in a black slot.
