Both A and D would be correct if there were four unique answers, but since A and D are the same answer, the chance that you would choose a correct answer is 50%, which makes B correct. But if there’s only one correct answer, the odds of choosing the correct one at random goes back to 25%.
What is the probability that a randomly selected question was answered correctly?
So, in general, the probability is zero, that for a random question, we give a correct answer.
What is the probability that you will correctly guess at least one question?
If there were just one question, then the probability of guessing correctly would be 1/3. Since all the answers are independent (the answer to one question has no bearing on the answers to the others), then this is the case with each question, so the chances of guessing all answers correctly is 1/3 × 1/3 × 1/3 = 1/27.
What is the probability that the person answers correctly at least 2 of the questions?
The probability of answer 2 or more correctly is 1- 0.5833740234375= 0.4166259765625.
What is the probability of choosing letter O in the word school?
In the word ‘school’, the letter o occurs twice. So the number of favorable outcomes is 2.
What is the conditional probability that his answer is correct and he knew it?
Answer: The probability that he knew the answer to the question, given that he answered correctly is 24/29.
What is the conditional probability that his answer is correct given that he knew it?
The probability that his answer is correct given that he copied it, is 1/8.
How do you pass a multiple-choice test?

- Use the process of elimination.
- Select the best answer.

- Answer the questions you know first.
- Make an educated guess.
What happens if you choose an answer at random?
With there being only two viable answers, you have a 50% chance of being correct if you guess between them. If you choose any answer, not just viable ones, then there are an infinite number of choices and the correct answer would be zero. It says you choose an answer at random, though, not choose from viable answers.
What is the chance you will choose the correct answer?
Closed 2 months ago. If you choose an answer to this question at random, what is the chance you will be correct? When limited to the 4 provided answers, there is no correct answer, because this question is a paradox. When there is one correct answer, the chance to pick that answer would be 25%.
What is the probability of picking the correct answer?
As it is repetitive, it could not be the answer to the question. If we can choose multiple answers, 25% could be included but it is not the case here. That gives us only 2 choices. So picking one in random of the options will be 50%. Note that I am not picking the option 50% but the probability of picking the right answer is 50%.
Is the probability of multiple choice question having option B as?
Two different answers say “25%,” so there are actually two correct answers. Two out of four is 50%, so the answer according to second level logic is 50%. Third level logic considers that both first and second level logic are correct to a point, or from a specific perspective.
