Question 1 • Mathematics II

Lola pulls two marbles from a bag containing four red marbles, four blue marbles, and 12 yellow marbles without replacing them. What is the probability that she pulled out a red marble first and a yellow marble second? Express your answer in decimal form, rounded to the nearest hundredth.

Answer
A
0 point 2 5
B
0 point 3 2
C
0 point 0 9
D
0 point 1 3

Explanation

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.”
