If you got 63 questions out of 84 questions what percent did you get wrong?
To find the percentage of questions you got wrong, first determine the number of incorrect answers by subtracting the correct answers from the total questions: 84 - 63 = 21 questions wrong. Then, calculate the percentage of wrong answers by dividing the number of incorrect answers by the total questions and multiplying by 100: (21/84) * 100 = 25%. Therefore, you got 25% of the questions wrong.
What is the probability of answering 50 questions right out of 100?
Depends on the questions, and how they are answered. T/F, multiple choice, matching, essay, etc. Could be randomly answering, making educated guesses, or applying some amount of knowledge on the subject. Each of these impacts the probability of supplying correct answers.
Under Binomial distribution a standard test consists of multiple choice questions with 5 possible choices. How do you ensure that a student who randomly guesses will obtain an expected score of 0?
In a Binomial distribution, if a student randomly guesses on multiple-choice questions with 5 possible choices, the probability of selecting the correct answer is ( p = \frac{1}{5} ) and the probability of selecting an incorrect answer is ( q = 1 - p = \frac{4}{5} ). The expected score for a student guessing on ( n ) questions is calculated as ( E(X) = n \cdot p ). To ensure that a student who randomly guesses has an expected score of 0, the number of questions ( n ) must be set to 0, or alternatively, the scoring system must be adjusted so that the expected value of scoring remains zero, such as by introducing penalties for incorrect answers.
Tristan guesses on two multiple-choice questions on a test if each question has five possibe answers choices what is the probability that he gets the first one correct and the second one incorrect?
4/25
What is the probability of getting all five answers correct if i have five multiple choice questions with four possible answers determine the number of possible answers?
The probability will depend on how much you know and the extent of guessing.

Students are required to answer 2 True of False questions and 1 multiple choice questions with 4 responses If the answers are all guesses what is the probability of getting all 3 questions correct?
The probability of correct true & false question is 1/2 and the probability correct multiple choice (four answer) question is 1/4. We want the probability of correct, correct, and correct. Therefore the probability all 3 questions correct is 1/2 * 1/2 * 1/4 = 1/16.

What is your percentage if you missed 11 questions out of 80 questions?
86.25% To verify: Divide number of incorrect questions (11) by number of original questions (80); answer expressed as a percentage is 13.75%. That's the number of incorrect answers, therefore 100% - 13.75% = 86.25% is the number of correct answers.
If you got 63 questions out of 84 questions what percent did you get wrong?
To find the percentage of questions you got wrong, first determine the number of incorrect answers by subtracting the correct answers from the total questions: 84 - 63 = 21 questions wrong. Then, calculate the percentage of wrong answers by dividing the number of incorrect answers by the total questions and multiplying by 100: (21/84) * 100 = 25%. Therefore, you got 25% of the questions wrong.
What are the odds against correctly guessing the answer to multiple choice question with 7 posssible answers?
6 to 1. (That is, 6 incorrect to 1 correct.) This is equaivalent to a probability of 1/7 or a 14% chance of guessing the correct answer.
What is the probability of answering 50 questions right out of 100?
Depends on the questions, and how they are answered. T/F, multiple choice, matching, essay, etc. Could be randomly answering, making educated guesses, or applying some amount of knowledge on the subject. Each of these impacts the probability of supplying correct answers.
