What is the probability that one of the two math multiple-choice questions is correct?
The probability of answering a question correctly is 1/4, and the probability of answering it incorrectly is 3/4.

If the first question is answered correctly, the probability is 1/4*3/4=3/ 16.

If the second question is answered correctly, the probability is also 1/4*3/4=3/ 16.

Therefore, the probability that the two answers are correct is 3/ 16+3/ 16=3/8.
