To find the probability of getting at least 6 correct answers on a 10-question multiple-choice exam where each question has 5 choices (with only one correct answer), we can model this situation using the binomial probability formula. The probability of guessing correctly on each question is ( p = \frac{1}{5} ) and incorrectly is ( q = \frac{4}{5} ). We need to calculate the sum of probabilities for getting exactly 6, 7, 8, 9, and 10 correct answers. Using the binomial formula, the probability ( P(X = k) ) for each ( k ) can be computed, and then summed to find ( P(X \geq 6) ). The resulting probability is approximately 0.0163, or 1.63%.
What else can I help you with?
In a multiple choice test what is the probability of getting two answers correct?
That depends on how many questions there are, how many choices are listed for each question, and whether any obviously-stupid answers are included among the choices. If any of those factors changes, then the probability changes. One thing we can guarantee, however, even without knowing any of these factors: If you have studied the subject and know the material, then your probability of getting correct answers increases dramatically.
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 getting 100 percent on a four question quiz?
If it is a T/F test; probability correct for each question is 0.5. Since there are 4 questions, raise 0.5 to the 4th power; e.g. (0.5)4. So, probability all correct is 0.0625. If a 4 part multiple choice, P(correct) = .25 so raise .25 to the 4th power, or .003906.
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 does an answer key look like?
An Answer Key is typically used for multiple choice tests. So if each question has A through D choices, the Answer Key would list the question number and the correct choice for each question. e.g.CAand so on.
What is the probability of guessing the correct answer to a multiple choice question if there are five choices?
Not sure what a mulitple choice qustion is but if it is anything like a multiple choice question, it is 1/5 or 20%. I strongly advise you to get a dictionary, learn to spell or use a spell checker.
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.
A multiple choice question has 5 choices if you gets 2 questions what is the probability of getting both correct?
Well they are independent events so it is the probability of getting a correct answer multiplied by the probability of getting a correct answer on the second question. Short Answer: 1/5 times 1/5=1/25
A multiple choice question has 4 choices What is the probability you can guess the correct answer?
1/4, or 25% 25%, 1/4 A, 1/4B. 1/4C, 1/4 D
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 guessing the correct answer to a multiple choice if there are five choices?
Not sure what a mulitple choice qustion is but if it is anything like a multiple choice question, it is 1/5 or 20%. I strongly advise you to get a dictionary, learn to spell or use a spell checker.
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
A test has 2 multiple choice questions each with 5 choices what is the probability of guessing the correct answers to both questions?
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.

In a multiple choice question with five possible answers what is the probability the correct answer will be found?
1/5 or 0.2
What is the probabi lity of guessing the correct answer to a multiple choice question if there are 5 choices?
It is 1/5.
What is an answer stem?
An answer stem is the part of a multiple-choice question that presents the initial information or prompt to which the answer choices are related. It typically poses a question or incomplete statement that the test-taker must respond to by selecting the correct answer choice.
