DIY Challenge 2
If we had 3 balls, we see that we can arrange them in 6 different ways.
We want to find the total ways to arrange if there were 4 balls. One way could be to write down or draw all the possible ways.
Can you think of an easier way to count the total number of ways to arrange 4 balls?
