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 science test, Jamie solved 42 correct answers out of 60. What is the percentage of correct questions? THIS IS NOT THE ANSWER THIS IS THE WORD PROBLOM
The probability that she gets exactly 3 right is 8C3*(1/3)3*(2/3)5 = 0.2731 approx.
5 incorrect answers and 15 correct answers
35%
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.
The probability will depend on how much you know and the extent of guessing.
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.
.237 or about 24 %
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.
you'd have a 50% chance of getting the 3rd and 4th question correct because you said the first 2 questions are already anwsered correctly :)

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.
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.
"Include in your credit references the answers to these questions" is correct. It is more natural, however, to say "Include the answers to these questions in your credit references."
50%
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.
