Comment on Fundamental Counting Principle Example

If we have 2 ways of sitting the girls in chair no. 1, don't we have 2 ways of sitting the girls in chair no. 5 too. Likewise, 3 ways for 2, 3, 4?. Just trying to look at the flip side too. Thanks.

Once we COMPLETE stage 1 (placing a girl is chair 1), then there is only ONE girl remaining.

So, when we start working on stage 2 (placing a girl in chair 5), we have only ONE way to complete this stage.

The same applies to seating the boys.

Does that help?
