Answer:
5/6 is the correct answer.
Step-by-step explanation:
⇒ No. of RED BALLS = x
⇒ No. of WHITE BALLS = 2x
⇒ No. of BLUE BALLS = 3x
⇒ Total no. of balls = 24
⇒ Balls other than RED = (2x + 3x) OR 24 - x
A/Q,
⇒ 2x + 3x = 24 - x
⇒ 5x + x = 24
⇒ 6x = 24
⇒ ∴ x = 4
No. of RED BALLS = 4
∴ Probability of Balls not being RED = (24 - 4) ÷ 24
= 20/24
= 5/6 ←ANSWER
