Answer» Correct Answer - Option 3 : Quantity I > Quantity II Calculation: Quantity I: Favorable outcomes: 2 brown + 1 red ball = 3C2 × 4C1 ⇒ 12 Total outcomes = 12C3 ⇒ 220 ∴ Probability = 12/220 ⇒ 3/55 Quantity II: 3 Orange balls = 5C3 ⇒ 10 Total outcomes = 12C3 ⇒ 220 ∴ Probability = 10/220 ⇒ 1/22 Quantity I > Quantity II |
