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 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 all five answers correct if i have five multiple choice questions with four possible answers determine the number of possible answers?
