If A and B are events of a random experiment with P(A)=0.5, P ( B )=0.4 and P ( A B )=0.3 , then the probability that neither A nor B occurs is

Options

  1. A0.04
  2. B0.4
  3. C0.8
  4. D0.2

Correct answer

B. 0.4

Step-by-step solution

We know, P(A B)=P(A)+P(B)-P(A B) P(A B)=0.5+0.4-0.3=0.6 So probability neither A nor B=1-0.6=0.4
