What is the probability of getting exactly 7 out of 12 multiple choice questions right if a student randomly guesses one of the five possible choices for each question?
It is 0.0033
If a student guesses on 10 questions on a multiple choice test abcd find the mean expected correct guess?
In a multiple-choice test with 4 options (a, b, c, d) for each question, the probability of guessing correctly for each question is ( \frac{1}{4} ). If a student guesses on 10 questions, the expected number of correct guesses can be calculated by multiplying the number of questions by the probability of a correct guess: ( 10 \times \frac{1}{4} = 2.5 ). Therefore, the mean expected correct guesses for the student is 2.5.
What is the probability that if you just guess on five multiple choice questions each with four possible answers you will get none of the questions correct?
.237 or about 24 %
What is the probability of getting a question right simple by guessing?
That depends a lot on the specific circumstances, of how you guess. For instance, if a test has true/false questions, the probability is 1/2; if it is a multiple-choice question with 4 options, the probability is 1/4; if there are 6 options, the probability is 1/6, etc.; if you have to calculate a number (and it is NOT a multiple choice question), the probability is rather low, indeed.
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.

Probability of getting all questions wrong on multiple choice test?
In order to answer, the number of questions on the test must be given.

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 the probability of getting five questions correct on a 20 question multiple choice test?
The answer depends on the number of choices available for each question.
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 ).

A student takes a six question multiple choice quiz with 4 choices for each question What is the probability that the student will answer exactly 4 correctly?
P = (6!)/(6-4)!4!=15
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.

64/256
