Probability of Event Not Happening
Suppose a random experiment results in n equally likely outcomes out of which m are favorable to the occurrence of an event A,Then the number of unfavorable outcomes will be:
Number of unfavorable outcomes = Total number of Outcomes - Number of favorable outcomes = n - m
If we denote the probability of occurrence of event A by P(A), then the probability of not occurrence of the event is denoted by P(A')
