can you add a line separating each row so that the solution can just be combinations vs permutations without having to specify that it is about rows
or the solution can be "rows in each box show all possible combinations of sorting dots into bins vs rows in each box show all possible permutations of sorting dots into bins"
In the box on the left with 6 bins, there are 5 empty bins and 1 bin with 1 dot. The position of the bin with 1 dot does not create a unique combination of bins because there are still 5 empty and 1 with 1.
In the box on the right with a 3 by 3 grid of bins, the position of the bin with the dot creates a unique permutation. 1-0-0, 0-1-0, 0-0-1 are considered unique on the right, but the same on the left.
A null box would fit on either side, as would any singular box with any amount of dots. (does that make this problem invalid?)
order of bins does not matter on the left, order of bins matters on the right |
