Answer 2

Okay so 2red, 5white, and 3blue. All together that is 10Marbles.
If you take one out and replace it then there is still 10marbles.
So you take the number of red (2) and the number of marbles (10) which equals the probabilty of 2/10 which can be redused to 1/5 and for blue you do the same thing which is 3/10
