Specify the number of events (N) and the probability of success on any one event (π). To find a cumulative probability, specify whether you want to find the probability of the number of successes to be less than or equal to a value, greater than or equal to a value, or between two values. When you ask for the probability between two values, both values are included. Therefore, the probability between 3 and 5 is the probability of 3, 4, or 5. To find the probability of three successes, find the probability between 3 and 3. The specified range is shown in red and the probability is displayed at the bottom.
