Question 1 • Mathematics II
There are 20 marbles total, so the probability of drawing a red marble first is 4/20. After that, 19 marbles remain, including all 12 yellow marbles, so the probability of drawing yellow second is 12/19. Multiply: (4/20) × (12/19) = 48/380 ≈ 0.126, which rounds to 0.13, the choice “0 point 1 3.”
