A multiple choice test consists of 10 questions each with four choices (a,b,c,d) for each question. If a student must get at least 7 correct to pass the test, what is the probability that a student could pass the exam simply by guessing? Find your answer to 4 decimal places.
Solution:- Given that n = 10, p = 1/4 = 0.25
P(X >= 7) = 0.0035

A student takes an exam containing 12 multiple choice questions. Each question has 5 choices. At least 8 correct answers are required to pass. If the student guesses, what is the probability that he will pass? Round your answer to four decimal places.
. There are n questions on a multiple choice exam, and for each question, there are four choices. To pass the exam, one must correctly answer at least 70% of the questions. The student has not studied, so he/she has to resort to guessing on every question. a. Find the probability of the student passing for n = 10. b. Find the expected number of questions answered correctly for n = 20. c. Find the variance for the number of...
A student is taking a multiple-choice exam in which each question has four choices. Assuming that she has no knowledge of the correct answers to any of the questions, she has decided on a strategy in which she will place four balls (marked A, B, C, and D) into a box. She randomly selects one ball for each question and replaces the ball in the box. The marking on the ball will determine her answer to the question. There are...
A multiple-choice examination consists of 75 questions, each having possible choices a, b, c, and d. Approximate the probability that a student will get more than 18 answers correct if he randomly guesses at each answer. (Note that, if he randomly guesses at each answer, then the probability that he gets any one answer correct is 0.25.) Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not...
Multiple-Choice Exam A student takes a 13-question, multiple-choice exam with two choices for each question and guesses on each question. Find the probability of guessing at least 9 out of 13 correctly. Assume the variable is binomial. Round the intermediate and final answers to three decimal places. P (guessing at least 9 out of 13 correctly) = x
A student takes an exam containing 10 multiple choice questions. Each question has 5 choices. If the student guesses, what is the probability that he will get less than 7 but more than 5 questions right? Round your answer to four decimal places.
A student takes a multiple choice test consisting of 5 questions where there are 4 choices per question. Also, each question is worth 20 points. Suppose the student guesses on each question. Let X be the number of questions the student gets correct. The probability distribution for X is given below. Find the probability that the student gets at least a 60 on the test. Give your answer to four decimal places.
An exam consists of 64 independent multiple-choice questions. For each question, there are five choices, with only one being correct. Suppose a student randomly guesses the correct answer to each question. (a) What are the mean and standard deviation of the number of successful guesses? (b) Use the normal approximation to find the probability that the student will correctly guess at most 10 correct answers.

A student takes an exam containing 10 multiple-choice questions. The probability of choosing a correct answer by knowledgeable guessing is 0.5. At least 6 correct answers are required to pass. If the student makes knowledgeable guesses, what is the probability that he will fail? Round your answer to four decimal places.
