yay extra mark on the test =)..... okay well when it comes to probability i find that i over think the problems, i mean mr.k did say how hard it is so i think there must be a crazy amount steps to get the answer...i think probability makes me nervous because i have no idea if im doing it right or not. especially when it comes to those word problems, i find i dont do the steps correctly and end up messing up a bunch of times. im hoping that tomorrow when we do the pre-test i will be able to find out where i go worng and try to perfect it. not to mention i have no idea when to use nPr or nCr ....
