Question 15
If the probability of an event is P, then the probability of its completmentry event will be
(a) P - 1
(b) P
(c) 1 - P
(d) $1 - \frac{1}{P}$

Solution

Since, probability of an event +probability of its complementry event =1 So, probability of its complementry event =1 -Probability of an event =1 -P
