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.

25/32 X 100 = 78% ( this, of course, is a raw percent. Your teacher may have his/her own ideas about grading )
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%
