Answer:
24 different ways
Step-by-step explanation:
You have to make a choice which ball to put in the first box. You have 4 options.
Then you must make a choice which ball to put in the second box. You have 3 options (there are three balls left)
Then you have to make a choice which ball to put in the third box You have 2 options (there are two balls left)
It isn't necessary to make a choice about the fourth box, because there's only 1 option (there's only one ball left)
So you have 4 choices for the first box.
For each of those 4 choices, you have 3 choices for the second box. That makes 12 number of ways.
For each of those 12 ways, you have 2 choices left for the third box. That makes 24 number of ways.
You have only 1 ball left for the fourth box, so that leaves you at ................. ....... 24 number of ways.
Hope this helps
