# Answer on Abstract Algebra Question for Rick H

Question #11473

A student is taking a 5 question T/F test. If the student chooses answers at random, what is the probability of getting all questions correct? I'd like to know the formula to solve.

Expert's answer

The probability of getting correct (or incorrect) answer in a T/F question is 1/2. So, the probability of getting all questions correct is

P = (1/2)^5 = 1/32.

P = (1/2)^5 = 1/32.
