you pick one marble from each group. how many outcomes are possible?
Answer
Explanation:
Step1: Count marbles in each group
The first group has 2 marbles, the second has 2 marbles, and the third has 5 marbles.
Step2: Apply counting - principle
The total number of outcomes when picking one marble from each group is the product of the number of marbles in each group. So we calculate (2\times2\times5). (2\times2\times5=(2\times2)\times5 = 4\times5=20)
Answer:
20
