Answer 1

1/16

Explanation:

The probability of getting a blue marble is :
`(3)/(5+3+2+2) = (1)/(4)`

As the marble is replaced in the box, the probability of getting a blue marble on the second round is
`(1)/(4)` too.

When you have mutliple events which are following themselves, you should multiply the probabilities of each event:

`(1)/(4) X (1)/(4) = (1)/(4X4) = (1)/(16)`
