Use the binomial distribution to determine the probability that a student will get at least 8 out of 10 questions on a ten question multiple choice test correct by just guessing if each question has four (4) choices. Assume that the student randomly guesses any of the four choices with a .25 chance of guessing the CORRECT choice.© BrainMass Inc. brainmass.com June 3, 2020, 9:47 pm ad1c9bdddf
