BOB time =)

as usual ... mr. k starts the unit with something simple and something i actually understand and then BAM ... i have no idea what is going on. LOL. what i really needed for this unit was a lot of practice and i mean LOTS of practice. erhm. the end was really complicated for me. especially the pretest today; like question number three; i was completely stumped when mr. k explained the solution. i wished that we would've done this unit right after combinatorics because when we started mixing combinatorics with probability i almost forgot what combinatorics was. haha *sigh* anyways. i wish everyone good luck tomorrow!! =)
