Question 217314: 1.How many different signal can be made from 6 flags of which 3 are white, 2 are red and 1 is blue, if each signal consist of 6 flags placed one above the other?
2.How many different signal can be made from 5 different flags. If a signal consist of 5 flags placed one above the other on a flagpole? Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! Let's look at the following first.
-----
How many different ways can you display 3 flags if all flags are different?
-----
If you let the first flag equal a, and the second flag = b, and the third flag = c, then those ways are:
-----
abc
acb
bac
bad
cab
cba
-----
How many different ways can you display 3 flags if 2 of the flags are the same?
-----
replace a with x and b with x to get:
-----
xxc
xcx
cxx
-----
In the first case, the answer was 3! = 3*2*1 = 6 ways.
In the second case, the answer was 3!/2! = 3*2*1/(2*1) = 3 ways.
