Suppose A and B are two events such that P(A B)= 3 25 and P(B-A)= 8 25 . Then, P(B) is equal to

Options

  1. A11 25
  2. B3 11
  3. C1 11
  4. D9 11

Correct answer

A. 11 25

Step-by-step solution

Given, P(A B)= 3 25 P(B-A)= 8 25 Then according to figure P(B)=P(A B)+P(B-A)P(B)= 3 25 + 8 25 P(B)= 11 25
