Question

given the probability of happening an event is 0.75 and what is the severity of non happening of an event e

Answer 1

p(E)+p(not E)=1
0.75+p(not E)=1
p(not E)=1-0.75. = 0.25

probability of happening an event and not happening an event is always equal to 1.

Answer 2

Given - The probability of happening an event

Find - The severity of non-happening of an event

Solution - The sum of the probability of happening an event and the probability of not happening an event is 1.

Keep the values in the formula to find the probability of severity of a non-happening of event.

0.75 + Probability of not happening an event = 1

Probability of not happening an event = 1 - 0.75

Performing subtraction

Probability of not happening an event = 0.25

Hence, the probability of severity of a non-happening of an event is 0.25.
