The probability of a student passing any examination is 2/3. If the student takes three examinations, what is the probability that he will not pass any of them?
2/3
4/9
8/27
1/27
Correct answer is D
P(pass) = 2/3
P(not pass) = 1 - 2/3 = 1/3
P(not passing any of the 3 Exams) = 1/3 x 1/3 x 1/3
= 1/27
