you flip a coin and pick a marble. how many outcomes are possible?

Explanation:

Step1: Determine coin - flip outcomes

A coin flip has 2 outcomes (heads or tails).

Step2: Determine marble - pick outcomes

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

The total number of combined outcomes is the product of the number of coin - flip outcomes and marble - pick outcomes. So, $2\times3 = 6$.
