Although this may sound like something technical, the phrase probability distribution is really just a way to talk about organizing a list of probabilities.

In other cases it is presented as a graph.
Probability density functions are used to describe the distribution of a random variable, i.e. the set of values a random variable takes and the probabilities associated with those values. This description of a random variable is independent of any experiment. For a value t not in the range of X, fX(t) = 0.
