Step-by-step explanation:

Count the number of outcomes from the coin toss. There are 2: heads or tails.

For each of those, there are 3 outcomes from the marble pick: R, Y, G. So the tree up to this point has 2·3 = 6 leaves:

  head - R

  head - Y

  head - G

  tail - R

  tail - Y

  tail - G

__

For each of these 6 outcomes so far, spinning the spinner will add 4 more. That will bring the total of possible outcomes to ...

  2 × 3 × 4 = 24 . . . outcomes

The short answer is that the total number of outcomes is the product of the numbers of possibilities at each stage.
