Question

IF the probability fo occurrence of an event is p then the probability of non-happening of this event is
(a) (p-1) (b) (1-p) (c) p (d) $(1-\frac{1}{p})$

Answer 1

Answer:

P(Event Not Happening)=1−P(Event Happening)

For any event:

P(Event Happening)+P(Event Not Happening)=1

Hence:

P(Event Not Happening)=1−P(Event Happening)

(b) 1-p
