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) (1, 2).
C) (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11).
Your answer: B was incorrect. The correct answer was C) (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.
Isn’t it B, because binomial means there can only be two outcomes (success / failure)?作者: chandsingh 时间: 2013-4-11 09:51
very tricky question, there are only two possible outcomes, but I believe the question is asking about the possible number of “successes” which would have to range from 0 to the number of attempts
