Pablo plays 3 rounds of a game, in which his chances of winning each round are 1/4, 1/8, and 1/n, respectively. If n ≠ 0, what is the probability that Pablo wins the first two rounds, but loses the third?  Choose the correct choice from the following choices.
A) 1/16n	B) (n-1)/32n	C) 1/8n	D) (n+2)/2n	E) (3n-2)/2n
1/4 * 1/8 * (1-1/n)   = 1/32 * (n-1)/n   = (n-1)/32n   Answer - (n-1)/32n
