Answer» Correct Answer - D Note that `A_(1)` is independent with all events `A_(1),A_(2),A_(3),A_(4)....,A_(12),` Now, total number of ordered pairs is 23. `underset(22)( underbrace((1.1),(1,2),(1.3),...,(1,11)))+(1,12)` Also that `A_(2),A_(3),andA_(3),A_(2)` are independent. Hence, there are 25 ordered pairs. |
