Solved A Multiple Choice Test Contains 25 Questions Each Chegg A multiple choice test has 25 questions, each with 5 possible choices, exactly one of which is correct. the test is marked by giving four points to each correct choice, and subtracting one point for each incorrect choice. Question a multiple choice test contains 25 questions, each with four answers. assume that a student just guesses on each question. what is the probability that the student answers more than 20 questions correctly? what is the probability that the student answers fewer than 5 questions correctly?.
Solved A Multiple Choice Test Contains 25 Questions Each Chegg In a multiple choice test with 25 questions and four answer choices each, the probability of guessing the correct answer to a single question is 1 4. Final answer: a. the probability that the student answers more than 20 questions correctly is extremely small and can be approximated to 0. b. the probability that the student answers fewer than 5 questions correctly can be calculated using the binomial distribution formula and is approximately 0.896. 3 86. a multiple choice test contains 25 questions, each with four answers. assume a student just guesses on each question. (a) what is the probability that the student answers more than 20 questions correctly? (b) what is the probability the student. Question: a multiple choice test contains 25 questions, each with 4 answers. assume a student just guesses on each question. (a) what is the probability that the student answers more than 20 questions correctly? (b) what is the probability that the student answers less than 5 questions correctly?.
Solved 4 A Multiple Choice Test Has 25 Questions Each With Chegg 3 86. a multiple choice test contains 25 questions, each with four answers. assume a student just guesses on each question. (a) what is the probability that the student answers more than 20 questions correctly? (b) what is the probability the student. Question: a multiple choice test contains 25 questions, each with 4 answers. assume a student just guesses on each question. (a) what is the probability that the student answers more than 20 questions correctly? (b) what is the probability that the student answers less than 5 questions correctly?. Explanation the probability of getting a correct answer on each question is 1 4. the probability of getting 4 correct answers out of 25 questions is (1 4)^4. calculate (25 choose 4) * (1 4)^4 * (3 4)^21. the probability is approximately 0.03. To find the probability that a student answers more than 20 questions correctly out of 25 by guessing on a multiple choice test with 4 answers per question, we can use the binomial probability formula. We have a multiple choice test with 25 questions, each with four possible answers. the student is guessing the answers, so the probability of getting a question right is 1 out of 4, or 0.25. Question: a multiple choice test has 25 questions. each question has 5 possible answers, only one of which is correct. a correct answer is worth 4 points, but a point is taken off for each incorrecta answers all 25 questions by guessing at random. translate this into a box model.
