Variables p = probability that the event occurs on a given trial Chance) How likely something (an event) is to happen Big Takeaway Probabilities can give you an indication of what is likely to happen, but they CANNOT tell you what will happen. This means the set of possible values is written as an interval, such as negative infinity to positive infinity, zero to infinity, or an interval like [0, 10], which represents all real numbers from 0 to 10, including 0 and 10.
