About Our Tutorials Stat Trek provides five free, online tutorials: Advanced Placement AP Statistics. The Probability tutorial covers probability theory in aw-shucks language. Clear explanations and pages of solve probability problems. The Simple Linear Regression tutorial is a pain-free introduction to regression. A probability of 0 means that there is zero chance that the event will occur; a probability of 1 means that the event is certain to occur.

Numbers between 0 and 1 quantify the uncertainty associated with the event. For example, the probability of a coin flip resulting in Heads rather than Tails would be 0.

Fifty percent of the time, the coin flip would result in Heads; and fifty percent of the time, it would result in Tails. F Distribution Calculator The F distribution calculator makes it easy to find the cumulative probability associated with a specified f value.
