Explanation:

• A student ran out of time on a multiple-choice exam and randomly guessed the answers for two problems. Each problem had 4 answer choices a, b, c, d and only one correct answer. What is the probability that he answered both of the problems correctly? Do not round your answer.

the probability of guessing 1 out of 4 answers is 1/4 or 25%, but there is also the possibility that he answered the second question correctly as well, so 1/4 x 1/4 =

1/16 or 6.25%
