Assuming the questions are answered at random, the probability is 0.000009, approx.
50C49*(3/4)^49(1/4)
It is 0.0033
.237 or about 24 %
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.
Multiple choice questions about pollution awareness could be asked in a general knowledge quiz. They my also be used in exam questions at school.
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.
It is 0.0033
In order to answer, the number of questions on the test must be given.

The probability of correct true & false question is 1/2 and the probability correct multiple choice (four answer) question is 1/4. We want the probability of correct, correct, and correct. Therefore the probability all 3 questions correct is 1/2 * 1/2 * 1/4 = 1/16.
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.
The answer depends on the number of choices available for each question.
P = (6!)/(6-4)!4!=15
The probability will depend on how much you know and the extent of guessing.

i believe it would be a (1/4)^5 chance. if youre going that route, good luck
