Quizplus · Accepted Answer

To find the probability that X is greater than 2, we need to subtract the cumulative probability of X being less than or equal to 2 from 1.

P(X > 2) = 1 - P(X ≤ 2)

From the given cumulative distribution function, P(X ≤ 2) = 0.44. Therefore,

P(X > 2) = 1 - 0.44 = 0.56

So the answer is choice D.
