The sum of the probability of happening of an event or not happening is always same this is true because the probability of happening an event is always come between 0 to 1.
An example: You could define a probability distribution for the observation for the number displayed by a single roll of a die. The probability that the die with show a "1" is 1÷6.
That's because there are six possible outcomes, and only one of those outcomes is a "1". Lets label the probabilities of all the possible outcomes for the single die.
Roll a "1": Probability is 1÷6
Roll a "2": Probability is 1÷6
Roll a "3": Probability is 1÷6
Roll a "4": Probability is 1÷6
Roll a "5": Probability is 1÷6
Roll a "6": Probability is 1÷6
Each probability is between 0 and 1, the sum of all the probabilities:
1÷6+1÷6+1÷6+1÷6+1÷6+1÷6=1,
So by this we can say that when we want to get not happening event so we have to subtract it from 1
FOR EXAMPLE :
If we want to calculate the not happening event in first role so we have so subtract it from 1
1-1÷6
5÷6
