Solved A Quiz Consists Of 10 Multiple Choice Questions Each Chegg A multiple choice quiz has 10 questions. each question has four possible answers. sam is certain that he knows the correct answer for questions, 3, 5, and 8. if he guesses on the other questions, determine the probability that he gets at least 50% on the quiz. A student takes a multiple choice test that has 10 questions. each question has four choices. the student guesses randomly at each answer. let x be the number of questions the student gets correct. (a) find p (x = 3). (b) find p (x> 2). (c) to pass the test, the student must answer 7 or more questions correctly.
Solved 3 There Are 10 Multiple Choice Questions With 4 Chegg (1 1 x) 10=.7 where x is the number of correct in the remaining 8 questions. solving for x gives x=5. so she has to get at least 5 questions correct by guessing. since each question has 5 possible answers the probability of guessing correctly is 1 5 or .2. Find step by step probability solutions and your answer to the following textbook question: a multiple choice test has $10$ questions each question has four answer choices. what is the probability of passing a test?. A multiple choice quiz has 10 questions. each question has four choices and only one of those is correct. if a student guesses on each question, find the probability that he will get at least 1 correct answer. First, let's find the probability of getting all 10 questions wrong. since there are 4 choices for each question, the probability of guessing the wrong answer for one question is 3 4.
Solved Question 10 A Quiz Consists Of 8 Multiple Choice Chegg A multiple choice quiz has 10 questions. each question has four choices and only one of those is correct. if a student guesses on each question, find the probability that he will get at least 1 correct answer. First, let's find the probability of getting all 10 questions wrong. since there are 4 choices for each question, the probability of guessing the wrong answer for one question is 3 4. Question: a quiz has 10 multiple choice questions. each question has 5 possible answers, one of which is correct. a correct answer is worth 8 points but 2 points are taken off for each incorrect answer. a student answers all the questions by guessing at random. a. the student's total score will be like the sum of draws from a box with what tickets?. A multiple choice quiz has 10 questions. each question has five possible answers, of which only one is correct. (a) what is the probability that sheer guesswork will yield at least 9 correct answers? (b) what is the expected number of correct answers by sheer guesswork? (c) suppose that 10 points are awarded for a correctly answered question. Question: a quiz has 10 multiple choice questions. each question has 5 possible answers, one of which is correct. a correct answer is worth 8 points but 2 points are taken off for each incorrect answer. a student answers all the questions by guessing at random. the student’s total score will be like the sum of draws from a box with what tickets?. To solve this, you first need to understand that each question has a 1 4 possibility of being correct (since there are 4 choices). so, the chance that the student gets it wrong is 3 4. the expected value (e) for correct guess is 1 point and for incorrect guess is 0.25 points.
