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.

What grade would you get for answering 21 out of 32 questions right?
65/100
How many questions do you need to get right for at least a score of 100 when answering 126 out of 126 gets a score of 176 answering 0 gets you 0 and answering 63 gets 88?
Assuming every question has the same score, then: if 126 questions correct score 176, each question scores 176/126 points With 0 correct this gives a score of 0 × 176/126 points With 63 correct this gives a score of 63 × 176/126 = 88 (as given). To score at least 100: number of questions × 176/126 ≥ 100 → number of questions ≥ 100 × 126/176 = 71 13/22 Assuming you cannot answer part of a question to get the mark, you must answer at least 72 questions to get a score of 72 × 176/126 = 100 4/7 If you were to get only 71 questions right you would score 71 × 176/126 = 99 11/63 which is less than 100. You need to get 72 questions right to get a score of at least 100.

There are five questions on a quiz with four possible answers what is the probability you get 100 percent?
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.

If a student guesses on all 5 questions on a tru-false exam what is the probability that he or she get them all right?
For each question the student has a 50% chance of answering right. We can express this as a fraction of 1 (1 being 100%): 1/2, i.e. 0.5 There are 5 questions, so the answer will be: 0.5*0.5*0.5*0.5*0.5=0.5^5=0.03125 or 3.125%
