you spin the spinner and pick a marble. how many outcomes are possible?

Explanation:

Step1: Determine spinner outcomes

The spinner has 4 sections, so there are 4 possible outcomes from spinning it.

Step2: Determine marble - picking outcomes

There are 3 marbles, so there are 3 possible outcomes from picking a marble.

Step3: Use the multiplication principle

The total number of combined outcomes is the product of the number of spinner outcomes and marble - picking outcomes. So, $4\times3 = 12$.

Answer:

12
