a multiple choice quiz consists of 20 questions, each of which has five possible answers of which only one is correct. A student passes the quiz if twelve or more correct answers are obtained. what is the probability of passing the quiz if on each question, a student can eliminate two incorrect answers and then guess between the remaining three? (answer format _._ _ _ _ _ _)
a quiz consists of 20 multiple-choice questions. each with 4 choices but only 1 answer, while a student decided to randomly guess all the answers in the quiz. 1. find the probability for passing the quiz when the passing grade is 60% 2. find the probability to get the first correct answer within the first 3 attempts 3. find the expected number of attempts to get the first correct answer
A quiz consists of 6 multiple-choice questions. Each question has 4 possible answers. A student is unprepared, and he has no choice but to guess answers completely at random. He passes the quiz if he gets at least 3 questions correctly. What is the probability that he will pass?
