Charlie the Chimp is taking a multiple choice test. There are four questions on the test and there are three answer choices for each question. Only one answer choice is correct for each question. Since Charlie is a chimp, he will be guessing on each question. As a common fraction, what is the probability that he guesses exactly one right answer?
