Question

If probability of an event is P the probability of its complementry event will be ​

Answer 1

Answer:

So, probability of its complementary event = (1 - Probability of an event) = 1 - P

Step-by-step explanation:

Answer 2

Answer:

Probability of complementary event  = 1 - p

Step-by-step explanation:

If the probability of an event is p the probability of its complementary event will be  →

Sum of Probability of an event and its complementary event = 1

⇒ Probability of complementary event = 1 - Probability of an event

⇒ Probability of an event = p

⇒ Probability of complementary event  = 1 - p
