Answer 1

A 2
B 4
C 8
D 16

Answer 2

Drawing a marble and tossing a coin are completely separate and independent events. Thus, you take the four possible marble draws and the possibility of obtaining a head or a tail and do ... what? ... with them? Key word here is "independent."

You could draw a diagram: starting with a red marble, show the possible outcomes that lie ahead: heads or tails.

Then do the same thing for the other 3 marble colors.

How many possible outcomes do you see now?
