I think the reason there are so little views is because most people watch these videos on the AOPS website, and not here.

Can I upload any problems that you can solve for me. I need some help in these.

You could do this easily by finding the total ways minus the ways that you touch the square using the formula for combinations ( like 10c5 for the total ways)

That solution is really unadvisable
