Leanna guesses on four multiple choice test questions in a row. Each question has 3 possible answers. What is the probability that Leanna will guess the answer to the 4th question correctly?
The fourth question is an independent event and that Leanna can choose from 3 choices. Only 1 of the 3 choices is right. Therefore, the probability of getting the correct answer is 1/3. The answer is letter C. 1/3.
