Carey can pick out C(30,5) or 142506 combinations
Step-by-step explanation:
Given
total CDs = n = 30
CDs to be selected = r = 5
the combinations are used to find ways anything can be chosen without order.
In the given case:
The combinations will be:
[tex]C(n,r)=\frac{n!}{r!(n-r)!}\\Putting\ values\\C(30,5)=\frac{30!}{5!(30-5)!}\\\\=\frac{30!}{5! * 25!}\\\\=142506\ combinations\\[/tex]
