Let the random variable X be the outcome of rolling a 6-sided die. Assuming the die is fair, the probability distribution is as follows:

X 1 2 3 4 5 6

Probability 1/6 1/6 1/6 1/6 1/6 1/6

Using the above table to answer the question: What is the probability that X is less than or equal to 2?

A.1/6

B.1/5

C.1/3

D.1/2

E.2/3
