A chemistry lab requires students to identify chemical compounds by using various tests. Each student is given samples of three different compounds, labeled A, B, and C. Each student is also given a list of seven possible compounds. If a student does not perform the tests and randomly chooses three from the list, what is the probability that he guesses all three correctly?
