Answer:
Step-by-step explanation:
Given that there are 15 people and they should be divided into two groups one with 10 and the other with 5 people.
First group 10 persons can be selected from 15 in 15C10 ways.
Remaining 5 would automatically be put in group 2.
Hence no of ways [tex]= 15C5 =\frac{15!}[10!5!} \\=3003[/tex]
