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 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.
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 getting five questions correct on a 20 question multiple choice test?
The answer depends on the number of choices available for each question.
How do you write an answer to a probability question?
Probability questions are not all the same so there is not a single kind of answer: it depends on the nature of the question!

What is the probability of getting a question right simple by guessing?
That depends a lot on the specific circumstances, of how you guess. For instance, if a test has true/false questions, the probability is 1/2; if it is a multiple-choice question with 4 options, the probability is 1/4; if there are 6 options, the probability is 1/6, etc.; if you have to calculate a number (and it is NOT a multiple choice question), the probability is rather low, indeed.
What is the probability of getting five questions correct on a 20 question multiple choice test?

A student takes a six question multiple choice quiz with 4 choices for each question What is the probability that the student will answer exactly 4 correctly?
P = (6!)/(6-4)!4!=15

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
