Three 192

Three separate containers each have one purple marble and two blue marbles. One marble is chosen from each box. Find the probability of selecting a blue marble from each box.

Correct answer:

p =  0.2963

Step-by-step explanation:

$$\begin{gathered} p_1=\frac{2}{1+2}=\frac{2}{3}\doteq 0.6667 \\ p=p_1\cdot p_1\cdot p_1=\frac{2}{3}\cdot \frac{2}{3}\cdot \frac{2}{3}=\frac{8}{27}=0.2963 \end{gathered}$$
