How much is the chance that a student would be able to answer a typical multiple choice item through guessing?

For every question, there are two outcomes: Either you answer correctly or you don’t. If you pick a random answer, the probability of guessing the right answer is one out of four, 1/4, or 0.25. Consequently, the probability of guessing wrong is a lot higher at 3/4 or 0.75.

How do you use multiple choice probability calculator?

Multiple Choice Probability Calculator. If you have carried out an assessment where someone makes a response by choosing from a set of possible responses (e.g. by pointing at a picture), you can use this to work out how likely they could have scored what they got on the test by chance.

Is it more likely to guess all answers correctly than wrong?

Although both are very unlikely, it is 3 times as likely to guess an answer incorrectly than to guess it correctly. So it is more likely to guess them all incorrectly than all correctly. (However, in a true-false test, they would be the same.)
