Answer: 12 outcomes total
Check out the diagram below
Edit: I added the tree diagram as well
===========================================================
Explanation:
I prefer to make a two way table for problems like this. Such diagrams make it fairly clear why multiplication is used when it comes to probability and counting problems.
Check out the diagram below.
The table has 6 rows and 2 columns.
The 6 rows represents the outcomes 1 through 6 on the number cube.
The 2 columns represent the outcome of heads (H) vs tails (T)
Inside the 6*2 = 12 inner cells, we'll have each outcome.
For example, the upper left corner has H1 to mean "flipped heads and got a 1 on the number cube". The next cell over is T1 to mean "tails on the coin, 1 on the number cube". The rest of the table is filled out in this manner.
The circumference of the top of the cake is in.
It sounds like the baker is trying to line the circumference with cherriesto fit as many as possible along the border, like in the picture I've attached below.
This comes down to dividing the cake's circumference by the diameter of each cherry:
or about 39 cherries, making the answer D.
