Using the Fundamental Counting Theorem, it is found that there are 576 ways for the dancers to line up.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with ways to be done, each thing independent of the other, the number of ways they can be done is:
In this problem, considering the order:
Black - Red - Black - Red - Black - Red - Black - Red
The number of ways for each is given by:
4 - 4 - 3 - 3 - 2 - 2 - 1 - 2
Hence:
There are 576 ways for the dancers to line up.

The given situation represents a random sample because, in statistics, a simple random sampling refers to the subset of individuals chosen from a larger set called population, where the sample is chosen randomly.
In this case, the dialed number are a random event, so it can be called a simple random sample.
