Answer:
1/16
Step-by-step explanation:
The probability of getting a blue marble is : [tex]\frac{3}{5+3+2+2} = \frac{1}{4}[/tex]
As the marble is replaced in the box, the probability of getting a blue marble on the second round is [tex]\frac{1}{4}[/tex] too.
When you have mutliple events which are following themselves, you should multiply the probabilities of each event:
[tex]\frac{1}{4} X \frac{1}{4} = \frac{1}{4X4} = \frac{1}{16}[/tex]
