Suppose E and F are two events of a random experiment. If the probability of occurrence of E is 1 / 5 and the probability of occurrence of F given E is 1 / 10 , then the probability of non-occurrence of atleast one of the events E and F is

Options

  1. A1 18
  2. B1 2
  3. C49 50
  4. D1 50

Correct answer

C. 49 50

Step-by-step solution

Given that, P(E)= 1 5 , P(F)= 1 10 Probability of both occurrence, P(E F)=P(E) P(F) = 1 5 1 10 = 1 50 Required Probability =1-P(E F) =1- 1 50 = 49 50
