A student guesses on every question of a multiple-choice test that has 8 questions, each with 4 possible answers. What is the probability that the student will get at least 6 of the questions right?
A student takes a 13-question, multiple-choice exam with two choices for each question and guesses on each question. Assume the variable is binomial. Round the intermediate and final answers to three decimal places Find the probability of guessing at least 9 out of 13 correctly P (guessing at least 9 out of 13 correctly) -
7. A student randomly chooses every answer on a 30-question multiple choice test. Which of the following reasons is needed to determine if this is a binomial distribution? (1 point) O The number of questions on the test is less than S0 Only one student is choosing to answer the questions randomly 0 The student is randomly choosing answers on only one test. O The outcomes can be divided into two categories: correct and incorrect 8. Assume that a procedure...
Assume that random guesses are made for 2 multiple-choice questions on a test with 5 choices for each question, so that there are n = 2 trials, each with probability of success (correct) given by p 0.20. Find the probability of no correct answers. Click on the icon to view the binomial probability table The probability of no correct answers is _______ (Round to three decimal places as needed.)
Assume that random guesses are made for six multiple choice questions on an SAT test, so that there are n=6 trials, each with probability of success (correct) given by p=0.4. Find the indicated probability for the number of correct answers. Find the probability that the number x of correct answers is fewer than 4. P(X<4)= ________ (round to four decimal places)
