Probability of occurance of an event at least once over n successive years is called RISK
📌RISK = (1- q^n)📌
p = Probability of occurance
= 1 / (Return Period T)
q = Probability of non occurance
= 1-p
ASSURANCE OR RELIABILITY is probability of non occurence of any event
Assurance = 1- Risk
📌RISK = (1- q^n)📌
p = Probability of occurance
= 1 / (Return Period T)
q = Probability of non occurance
= 1-p
