Answer 1

[AI-generated answer — Bot GPT 3.5]

To calculate the number of different lineups possible, we can use the combination formula:

nCr = n! / r!(n-r)!

In this case, n = 9 (total number of songs) and r = 8 (number of songs to be selected):

9C8 = 9! / 8!(9-8)!
9C8 = 9! / 8! * 1!
9C8 = 9
9C8 = 9

Therefore, there are 9 different lineups possible for the event's musical entertainment lineup.
