If the probability of an event A is 0.7, what is the probability of its complementary event A'?

Back

The probability of the complementary event A' is 0.3 (1 - 0.7).

Front

What is the formula to find the probability of complementary events?

Back

P(A') = 1 - P(A), where P(A') is the probability of the complementary event.
