Correct Answer - Option 4 : 1/16

**Given:**

Number of yellow balls = 5

Number of white balls = 4

Number of green balls = 7

**Calculation:**

Total number of balls in the box = (5 + 4 + 7) = 16

Number of ways to choose 3 balls from the box = 16C3 = 560

Number of green balls in the box = 7

Number of ways to choose 3 green balls = 7C3 = 35

∴ Required probability = 35/560 = 1/16
