first question:

i HATE Probability
1. probability of getting 1st orange sweet = 6/n
2. probability of getting 2nd orange sweet = 5/(n-1)
probability of both = 1. x 2. = 30/(n^2-n) = 1/3
30 = n^2 - n/3
90 = n^2 - n
n^2 - n - 90 = 0
3. just draw the probability tree and work from there

still can't believe that this question caused such a riot...
