Final answer:
There are 8 songs that Allan wants to arrange on the playlist. The number of ways to arrange them is 8! (8 factorial), which equals 40,320 ways.
Step-by-step explanation:
There are 8 songs that Allan wants to arrange on the playlist. To calculate the number of ways to arrange the songs, we use the concept of permutations. The number of permutations of a set of objects is given by n!, where n is the number of objects. In this case, Allan has 8 songs, so the number of ways to arrange them is 8!.
Calculating 8! we get:
8! = 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 40,320.
Therefore, the correct answer is A) 40,320 ways.
