Question

Solve.

A bag contains 2 red, 4 blue, and 4 yellow marbles. What is the probability of pulling a red marble, then a blue marble from the bag? (to the nearest tenth)

8.1
8.6
8.9

Answer 1

Answer:

8.9%

Step-by-step explanation:

Probability of picking a red marble first: $\frac{2}{10}=\frac{1}{5}$

Probability of picking a blue marble (no replacement): $\frac{4}{9}$

$\frac{4}{9} *\frac{1}{5} =\frac{4}{45} = 8.8888888888...%$ % ≈ 8.9%
