Option 4 : All I, II and III

From statement I and II and III

Three balls can be drawn from 13 balls in ¹³C₃ways

The number of ways of drawing three ball of different color = ⁶C₁ × ³C₁ × ⁴C₁= 72

Required probability = 72/¹³C₃ = 72/286

So, the number of ways of drawing three ball of same color = 1 - (72/286)

∴ All the three statements are required to answer the question
