you pick one marble from each group and roll a die. how many outcomes are possible?
Answer
# Explanation:
## Step1: Determine marbles outcomes
There are 2 marbles in the first - group and 2 marbles in the second - group. By the multiplication principle for independent events of picking marbles, the number of ways to pick marbles from the two groups is $2\times2 = 4$.
## Step2: Combine with die - roll outcomes
A die has 6 possible outcomes. When we combine the marble - picking outcomes with the die - roll outcomes, again using the multiplication principle for independent events, the total number of possible outcomes is $4\times6$.
$4\times6=24$
# Answer:
24
