You are taking a multiple choice test with 10 questions, with 4 different options per question. For each question, there’s only one correct answer. You haven’t studied for the test and you decide to choose the answers at random (each option equally likely). What is the probability that you get at least 7 of them right?

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

12. In an entrance examination with multiple choice questions, with each question having four options and a single correct answer, suppose that only 20% candidates think they know the answer to one difficult question and only half of them know it correctly and the other half get it wrong. The remaining candidates pick one option out of the four randomly and tick the same. If a candidate has correctly answered the question, what is the (conditional) probability that she knew...
