Problem: Suppose Ari loses 40% of all chess games.
(a) What is the probability that Ari loses two chess games in a row?
(b) What is the probability that Ari loses four chess games in a row?
(c) When events are independent, their complements are independent as well. Use this result to determine the probability that Ari loses four chess games in a row, but does not lose five in a row.
