How many times does an event not occur?
If an event occurs 0 times (out of 50, in this case) then it does not occur at least once. So we can find the probability of it not occurring and then subtract that value from 1. So, what are the chances of it not occurring on 1 trial? 1 − .116 = .884
What is the probability of an event not happening?
A probability of 0 means that the event is impossible to occur. The probability of an event occurring can never be more than 1. A probability of 1 means that the event is certain to occur. Complementary events are events that are opposite of each other and both can’t occur at the same time.
