Bobbing on Probability

Class was pretty helpful 'today'. I too had trouble deciding whether to use
the combination or permutation formula on certain problems but it is a bit
more clarified now. It can get a little bit tricky but next time I guess I should
just read the question more carefully. And to remember on certain problems
whether to use pick or choose.. maybe I should think that "picking" is
somewhat like favouring a person or a thing when selecting a person onto a
team or whatever (order matters). And "choosing" as the opposite... choosing
people without care of who you choose and what order haha. Well that's
just my interpretation of it. =] Good luck on the test everyone.
