Two brothers X and Y appeared for an exam. Let A be the event that X has passed the exam and B is the event that Y has passed. The probability of A is 1 7 and of B is 2 9 . Then, the probability that both of them pass the exam is

Options

  1. A1 63
  2. B2 35
  3. C2 63
  4. D9 14

Correct answer

C. 2 63

Step-by-step solution

Given, A be the event that x is selected and B is the event that y is selected. P(A)= 1 7 , P(B)= 2 9 Let C be the event that both are selected. P(C)=P(A) P(B) as A and B are independent events = 1 7 ( 2 9 )= 2 63
