An instructor develops a True-False exam for an introductory stat course. A student, who didn't
study, randomly guesses on each question. Making the reasonable assumption that the
probability of success (guessing correctly) on each question is equal to .5, answer the following
questions.
E) What is the probability that the student will score 14 or above?
F) What single score is the most likely? And what is the probability of obtaining this score?
G) If there is only one question (N = 1), what is the probability of getting 100% by guessing?
H) If there are two questions, what is the probability of getting 100%?
I) If there are five questions, what is the probability of getting 100%?
J) If there are 10 questions, what is the probability of getting 100%?
