Question

Find number of Non-negative integral solutions of a+b+c=8 where a > b.
​

Answer 1

Answer:

Step-by-step explanation:

Total number of non-negative integral solutions = (n+r-1) $C_{n}$  = (n+r-1)$C_{r-1}$

n= 8; r= 3

                          = (8+3-1)$C_{8}$

                          =10$C_{8}$ = 10.9/1.2=45

there are 45 non-negative integral solutions
