Pablo plays 3 rounds of a game, in which his chances of winning each round are 1/5, 1/3, and 1/n, respectively. If n ≠ 0, what is the probability that Pablo wins the first two rounds, but loses the third? Select.
A) 1/30n B) (n-1)/15n C) 1/5n D) (n+2)/3n E) (3n-2)/5n
1/5 * 1/3 * (1-1/n)   = 1/15 * (n-1)/n   = (n-1)/15n   Answer - (n-1)/15n
