Hi Charles, can you please give some more examples of the harder questions? Or link me to a video where I can further practice those?

i.e. If a committee of 3 people is to be selected from among 5 married couples so that the committee does not include two people who are married to each other, how many such committees are possible?

On question 1 - How come when working out the number of groups of 3, you don’t do 10x9x8x7x6x5x4x3x2x1 divided by 3x2x1? I saw you only did 10x9x8 and just trying to figure out why
