Consider the following cumulative distribution function for the discrete random variable X.  What is the probability that X is greater than 2?
A) 0.14 
B) 0.30 
C) 0.44 
D) 0.56

Quizplus · Accepted Answer

To find the probability that X is greater than 2, we need to subtract the cumulative probability up to 2 from 1:
P(X>2) = 1 - P(X≤2) = 1 - F(2) = 1 - 0.44 = 0.56
Therefore, the answer is D.
