You have a 4 percent chance of guessing both answers correctly assuming there is only one correct answer to each question and that you may only answer once per question.

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.
A multiple choice question has has 5 choices What is the probability of guessing it correctly?
There is 1 right answer out of 5 possible answers, so the probability of guessing it correctly is 1/5 or 20% or 0.2.
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.
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.
A test has 5 multiple choice questions each with 4 choices what is the probability of guessing exactly 3 out of 5 right?
Since there are 4 choices the probability of guessing any given answer correctly is 1/4 or .25; call this a success and denote it by p The chance of guessing wrong is .75; call this a failure and denote it by q. So the chance of 3 out of 5 correct answers is 5C3xp^3q^(5-3)=10p^3q^2 5C3x(.25)^3(.75)^2 5x4x3/3x2(.15625)(.5625) 10(.12625)(.5625)=.0877891

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 %
A test has 2 multiple choice questions each with 3 choices what is the probanility of guessing the correct answers to both questions?
The probability of getting both answers correct is one chance in nine (0.1111+). There are three possible answers for each question, so there is a 1/3 chance of getting the correct answer to one question. To get the correct answer for both questions, the chances are 1/3 x 1/3 or 1/9.
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 that a student would get more than 30 answers corredt simply by guessing in true of false?
To answer this, the total number of questions on the test would need to be known.

Georgia is taking a 5 question multiple choice quiz in which each question has 4 choices She guesses on all questions What is the probability that she answers exactly 2 of the questions correctly?
64/256
What has one purpose to organize the answers to what if questions?
An hypothesis starts out as a what if. So does guessing.
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.
A multiple choice quiz consists of 6 questions each with 4 possible answers If a student guesses at the answer to each question then the mean number of correct answers is?
If there are four possible answers to a question, then a guessed answer would have a probability of 1 in 4. If there are six questions, then the mean number of correct answers would be six times 1 in 4, or 1.5
