Question

3. Use Structure Shari is drawing a tree diagram

Answer 1

The sample space of Shari's tree diagram is the total possible outcomes of rolling the game piece and spinning the pointer.

It doesn't matter if Shari starts with the spinner or the game piece

How to determine the tree diagram

The experiment involves:

• Rolling a 12-sided game piece
• Spinning the pointer of a 4-section spinner

If Shari starts with the game piece, the sample size (n) would be:

n = 12 * 4

n = 48

If Shari starts with the spinner, the sample size (n) would be:

n = 4 * 12

n = 48

Notice that the sample size remains unchanged irrespective of what he starts with

Hence, it doesn't matter if Shari starts with the spinner or the game piece
