o% information incomplete
100*4/22 = 18.1818... (recurring) % wrong.
You would have gotten 73% of the questions correct, which in most places would get you a C.
Missing 4 out of 20 means you missed 20%.
You can only miss 16 points on a 100 point test in order to get an 84%. If the questions are worth 2 points EACH, you can miss 8. If the questions are worth 4 points each, you can only miss 4 questions.
If there are four possible answers to a question, then a guessed answer would have a probability of 1 in 4. If there are six questions, then the mean number of correct answers would be six times 1 in 4, or 1.5
75%
To get seventy percent or better on a quiz of 16 questions one needs 11.2 answers correctly answered. So it is best not to miss 4 but definitely not to miss 5 or more. This answer is arrived at by taking the 16 questions and multiplying by .70 (70 percent) or 16 x .70 = 11.2.
40% of 10 = 4 So four questions out of ten is answered correctly.

4/5.
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.
P = (6!)/(6-4)!4!=15
