Consider a 7 question multiple choice test with 5 possible answers for each question. Only one of the possibilities is correct. Assume that the student guesses without any knowledge of the questions or the answers.

Calculate the probability that the student guesses the correct answer to exactly four questions, at most four questions, and at least four questions using STATDISK

a. P(x) P(x or fewer) 4 0.1167984 0.9510727 P(x or greater) 0.1657257
b. X P(x) P(x or fewer) 4 0.0576782 0.9871216 P(x or greater) 0.0705566
c. P(x) P(x or fewer) P(x or gregter) 4 0.0660603 0.9894186 0.0856417
d. P(x) P(x or fewer). P(x or greater) 4 0.0057244 0.9994855 0.0062389
e. x P(x) 4 0.015778 P(x or fewer) P(x or greater) 0.9975177 0.0182602
f. X P(x) P(x or fewer) 4 0.028672 0.995328 P(x or greater) 0.033344
