Use the following information for questions:
In an experiment, a person guesses which one of three different cards a researcher has randomly picked (and hidden from the person who guesses). This is repeated four times, replacing the cards each time. Let X = number of correct guesses in the four tries. The probability distribution for X, assuming the person is just guessing, is partially provided below.
-What is the value of P(X $\le$ 2) = probability that number of correct guesses is less than or equal to 2?
