Binomial Distribution

Hello guys The question below seems simple, but I dont understand the answer. Could sb explain how to receive the below answer? Thanks Which of the following could be the set of all possible outcomes for a random variable that follows a binomial distribution? A) (-1, 0, 1). B) (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11). C) (1, 2). Your answer: C was incorrect. The correct answer was B) (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11). This reflects a basic property of binomial outcomes. They take on whole number values that must start at zero up to the upper limit n. The upper limit in this case is 11. This question tested from Session 3, Reading 9, LOS f

Answer C would have been correct if it had 0 in the exhaustive list. Basically, the list of outcomes have to be exhaustive. B has the entire list from 0 to 11. Toss a coin 11 times. Define a success as a Head showing up. Whats the exhaustive list of outcomes for 11 trials? It has to be zero thru 11.

Thanks! I got it now.
