Question

A and B are the only two outcomes of an event . If P(A)=0.72 then find P(B)

Answer 1

Step-by-step explanation:

Given:

P(A)=0.72

As, we know that maximum probability for occurrence of any event is 1.

∴ P(A) + P(B) = 1

⇒ 0.72 + P(B) = 1

⇒ P(B) = 1 - 0.72

⇒ P(B) = 0.28

Answer 2

P(B)=1-0.72

P(B)=0.28
