There are five questions on a quiz with four possible answers what is the probability you get 100 percent?
Probability of each question correct is 1/4 or 0.25. Since there are 5 questions, raise 0.25 to the 5th power or (0.25)5. So, probability all correct is 0.0009765.
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 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.
What are the odds of getting 100 percent on a 10 question multiple choice test where each question has 2 possible answers?
Assuming you reply each answer randomly, your probability is (1/2)10 = 1/1024 (about 0.1%). Of course, if you have at least some idea about some of the questions, your chances improve (you will have to guess on less questions).
If you have five multiple choice answers and all the combination put together equal 31 why is it 31?
If you have 5 questions, each with only two possible answers, the total number of combinations is 2*2*2*2*2 or 2^5 = 32. If the questions are all multiple choice and independent (ie no filters), then the total number of combinations must be the multiple of the numbers of choices for the questions.
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 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
In a multiple choice question with five possible answers what is the probability the correct answer will be found?
1/5 or 0.2
A multiple choice test has 8 questions that has 3 possible answers only one is correct If Judy who forgot to study for the test guesses on all questions what is the probability that she gets 3 right?
The probability that she gets exactly 3 right is 8C3*(1/3)3*(2/3)5 = 0.2731 approx.
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 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.
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.
