i would like to know the difference here (this is no longer a homework question but rather concept differentiation)
we know that probability = s/n (where s = success and n = total outcomes)
in this question:
For a certain style of new automobile, the colors blue, white, black, and green are in equal demand. Three successive orders are placed for automo- biles of this style. Find the following probabilities a One blue, one white, and one green are ordered. b Two blues are ordered. c At least one black is ordered. d Exactly two of the orders are for the same color.
the "n" is simply 4 x 4 x 4 = "64" in each letter
while in this type of question
An assembly operation for a computer circuit board consists of four operations that can be performed in any order. a In how many ways can the assembly opera- tion be performed? b One of the operations involves soldering wire to a microchip. If all possible assembly orderings are equally likely, what is the probability that the soldering comes first or second?
the "n" in letter b is "24" (which is simply 4! or 4 x 3 x 2 x 1)
whats the difference of n between the 2 questions. im having difficulty to understand n here.
