The probability of a student passing any examination is 23. If the student takes three examinations, what is the probability that he will not pass any of them?
Answer Details
The probability of a student passing any examination is 2/3. Therefore, the probability of the student not passing any examination is 1 - 2/3 = 1/3. Since the student is taking three examinations, we can assume that each examination is independent of the others. Therefore, the probability of the student not passing any of the three examinations is (1/3) * (1/3) * (1/3) = 1/27. So, the answer is 1/27.
