Hey Tony, thanks for the help on that question. I forgot to raise the 2 to the (-2x). So I was having quite the problem. Your approach was a hell of a lot faster than mine. Good help.

Yeah I appreciate your help Stuart. Also, your reasonning for an educated guess was what I actually did when taking the timed exam. Could you take a look at the question I posted: Permutation and Combination Manhattan. Thanks.

Combination and Permutation Manhattan
Bill has a small deck of 12 playing cards made up of only 2 suits of 6 cards each. Each of the 6 cards within a suit has a different value from 1 to 6; thus, there are 2 cards in the deck that have the same value. Bill likes to play a game in which he shuffles the deck, turns over 4 cards, and looks...

Re: Inequality question...tough one
If x is not equal to 0, is |x| less than 1? (2) The second statement says that |x| > x . The only way for this to be true is for x to be a negative number. But how do you know from this statement that x=-0.5 or -3. x= -0.5 means that |x|=0.5 which is less than 1 but if x=-3 then |x|=3 which is grea...

Re: Semi-hard probability question.
For 50% distribution why do you divide the possible outcome (nCk) by 2^n? If (prob wanted result) is 1/2, why then is it two? For a non-50% distribution you said (prob wanted result)^k * (1-prob wanted result)^(n-k). And in your example of the probabilty of it raining is 2/3, the (prob wanted result...
