Answer: 10
Step-by-step explanation:
- C(m,n) are used to denote a binomial coefficient. It is the number of ways of selecting n outcomes from n possibilities without being in order or sequence.
The value of the binomial coefficient for non-negative m and n is given by:-
[tex]C(m,n)=\frac{m!}{n!(m-n)!}[/tex]
Therefore, the value of C(5, 2) is given by :-
[tex]C(5, 2)=\frac{5!}{2!(5-2)!}=\frac{5\times4\times3!}{2\times3!}=10[/tex]
Hence, C(5, 2)= 10
