   S.MD.3.  (+) Develop a probability distribution for a random variable defined
for a sample space in which theoretical probabilities can be calculated;
find the expected value. For example, find the theoretical probability
distribution for the number of correct answers obtained by guessing on
all five questions of a multiplechoice test where each question has four
choices, and find the expected grade under various grading schemes.
