A multiple choice test is given, in which each question has 5 possible answers. As part of an experiment in how students approach test-taking, the probabilities for getting answers correct just by guessing are calculated. If the test has 20 questions, what is the probability of getting 4 questions correct

A multiple-choice test has 20 questions. Each question has 4 possible answers, of which only one is correct. (i) If you randomly answered each question, what is the name of the distribution for the number of possible marks you could achieve for the whole test? Explain your reasons and give the values for the parameters of that distribution.* (ii) If the pass mark for the test is 60% (i.e. 12 marks or more), what is the probability that you will...

When taking multiple choice test with 4 options for answers, there is a 25% chance that you will get the question right just by random guess. You wish to determine how many correct answers you can get just by random guessing on a 100 question multiple choice test. np>10np>10, At least 10 expected successes. n(1−p)>10n(1−p)>10, At least 10 expected failures. Approximate with N(np,np(1−p)) Binomial Distribution None of the above. Normal Population Distribution Uniform Distribution
