CFA Practice Question

BeigeBox, a computer manufacturer, can construct computer systems with any one of 4 processors, 2 memory configurations, 3 hard drives, 2 monitors, 2 keyboards, and 2 CD drives. How many unique configurations of computer systems can BeigeBox construct?
A. 192
B. 96
C. 384
Explanation: The multiplication rule of counting states with the number of combinations available when there are n_1 options in one aspect, n_2 in another, and so on, up to n_k, is n_1 * n_2 * ... * n_k. In this case, the number of combinations is 4*2*3*2*2*2 = 192.

sunnyhui this question is tricky cause people can have more then 1 cd drive so i feel like the author obviously dont know anything about computers
abs013 Who the hell needs to keyboards?
jacojacobs Sunnyhui, the question reads "any one of.." meaning you just get one of each, therefore only 1 CD drive, and only 1 of every item.
