bio statistics question!

Does P(x) = x/5, where x can take values of 0, 1, 2, 3, describe a probability distribution?

Would the answer be no because when x is 1, 2, or 3 the values become 0.2, 0.4, and 0.6. But in probability distribution the values have to be between 0 and 1?

    Aren't they between zero and one?
