Question

If the probability of happening of an event is P(A) then what is the probability if it's not happening?​

Answer 1

Step-by-step explanation:

p(A)+p(A')= 1

then,p(A')= 1-p(A) [here p(A') is probability of not happening of an event]

Answer 2

Answer:

1-P(A)

____________________________

Step-by-step explanation:

let the probability of happening be P(A)

let the probability of not happening be P(B)

we know that,

probability of happening + probability of not happening = 1

P(A) +P(B) =1

∴ P(B) = 1 - P(A)

ie, probability of not happening = 1 - probability of happening
