प्रश्न
One of the two events must happen. Given that the chance of one is two-third of the other, find the odds in favour of the other.
उत्तर
Let the given events be A and B
Now,
∴ P(A) or P(B) = 1
⇒ P(A) + P(B) = 1 (∵ A and B are mutually exclusive)
This implies that the odds in favour of B are 3 : (5 – 2), i.e. 3 : 2.
