Sagot :
- [tex]\tt{495\:ways}[/tex]
=================================
Solution
We use combination since order doesn't matter
n = 12, r = 8
12nCr8: 495
[tex]{}[/tex]
Total dishes = 12
We have to select 8
8 dishes from 12
= [tex]\large{ \tt{ \frac{12!}{8!(12\:-\:8)!}}}[/tex]
= [tex]\tt\large{ \frac{12!}{8!\:4!}}[/tex]
= [tex]\boxed{ \tt{ \underline{495\:ways}}}[/tex]
