### b-O-b

Okay, so this unit was all about counting. On the very beginning of this unit, I kinda have trouble with it, I didn't understand anything that day, but it's all good now. My muddiest point would probably be what formula to choose from the "pick" or the "choose" formula, and, whether to add or multiply the combinations or permutations. Everything else was pretty much straight forward. So good luck to all.
