Answer:
(D) Two players of equal skill level each played one game a day for 50 days and their skill level did not change from day to day.
Step-by-step explanation:
(A) If the player's skill improves over time, the likelihood of him winning the game also increases and, therefore, this scenario cannot be modeled by a random binomial probability.
(B) Since the players have different skill levels, the likelihood of winning each game would change between players, thus X is not a binomial random variable.
(C) Same explanation as alternative B
(D) Since both players have the same constant skill level throughout all games, the likelihood of winning each of the 100 games is the same; therefore, X is a binomial random variable
(E) Same explanation as alternatives B and C
