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.
