3 songs can be selected in 56 ways
Step-by-step explanation:
When the selection has to be made without order combinations are used.
The formula for combination is:
[tex]C(n,r) =\frac{n!}{r!(n-r)!}[/tex]
Here
Total songs = n = 8
Sons to be selected = r = 3
So,
[tex]C(8,3) =\frac{8!}{3!(8-3)!}\\=\frac{8!}{3!*5!}\\=56[/tex]
Hence,
3 songs can be selected in 56 ways
