Answer 1

There are 10 marbles in the bag.

Your chance of pulling a red one is 3/10 (3 red out of 10 possible).

Your chance of pulling a blue one is 2/10 (2 blue out of 10 possible).

Note: There are 10 possible when you pull out the blue only because you put the first red marble back.

3/10 * 2/10 = 6/100 or 3/50.
