App description

Probability of a single event

A is the probability of writing a single event as P(A), p(A) or Pr(A)

Single event supplement probability

The opposite or supplementary event A is an event, event A does not occur, and its probability is given by P(not A) = 1 - P(A)

Usage example

Input data: impossible result -n:5; number of events did not occur n(A): 4   Output result: probability of occurrence of event P(A): 0.8; probability of event not occurring P(A'): 0.2

Note

The number of events did not occur less than the impossible result.
