Question

If a and b are complements, then which of the following is true about the probability of b based on the probability of a?

Answer 1

Answer:

Option 2 is true.

Step-by-step explanation:

Th sum of probabilities of two complementary events is one, which implies

P(A) + P(B) = 1

So,

P(B) = 1 - P(A)
