Using the permutation formula, it is found that there are 17,297,280 different signals consisting of 8 flags.
In this problem, the order in which the flags are visited is important, hence the <em>permutation formula</em> is used to solve this question.
<h3>What is the permutation formula?</h3>
The number of possible permutations of x elements from a set of n elements is given by:

The first flag is blue, then the remaining 7 are taken from a set of 14, hence:

There are 17,297,280 different signals consisting of 8 flags.

Step-by-step explanation:
y - 3 = -1(x- -2)
y-3 = -x -2
Y = -x +1
