Probability Histograms (Jump to: Lecture | Video )

Probability Distribution

A probability distribution displays the probabilities associated with all possible outcomes of an event.

Here's a probability distribution for one roll of a six-sided die:

Figure 1.

As you can see, every event has an equal chance of occuring.

Probability Histogram

A probability histogram is a histogram with possible values on the x axis, and probabilities on the y axis.

Here's a made-up probability distribution(left) with its probability histogram(right):
