Hi all class mates:) counting it is confusing me i dont really now wich formula to use. I see all of the formulas amd i think of them the same. the pic(P) and the choos (C) formula i dont now wen to apply them wen given a question. I see the question clear wen i see the answer but wen i try to do it i get confused and think the question is complicated. I think doing assignments in groups helps because we can have a disction about how to do the problem and get help from the class mate and ask questions. well i wish every body good luck on the test and onle 2-3 more units to go.
