1. Both marbles are red.
2. Both marbles are yellow.

There are 6 total marbles/

1. 1/2 (the chance of drawing a red marble) * 2/5 (chance of drawing a second) = 1/5

 

2. 1/3 (chance of drawing a yellow marble) * 1/5 (chance of drawing a second) = 1/15

 

3. 2/3 (chance of not drawing yellow) * 3/5 (chance of not drawing a second yellow) = 2/5
