Help with probability problems:

1.) There are 20 red and blue marbles in a bag.

10 red marbles are numbered 1-10 and the 10 blue marbles are numbered 1-10.

Draw two marbles from the bag without replacing the first marble.

Find the probability that you select the blue marble labeled #7 on the first draw, and the red marble labeled #3 on the second draw?

2.) There are six shirts in a box.

Three are green; small, medium, and large, three are orange also labeled small, medium, and large.

Pick two shirts from the box but, replace the first shirt before drawing the second one.
