Question

Evaluate. 15C5= (answer with no camas or decimals)

Answer 1

Answer:

 $^{15} C_{5} = 3,003$

Step-by-step explanation:

here , we want to evaluate the value of 15 combination 5

Mathematically, we have the general combination formula as follows;

${n} C^{r} =\frac{n!}{(n-r)!r!}$

In this case , n is 15 and r is 5

Thus , we have it that;

$^{15} C_{5} = \frac{15!}{(15-5)!5!} \\= \frac{15!}{10!5!} =\frac{15x14x13x12x11x10!}{10!5!} \\=\frac{15x14x13x12x11}{5!} \\\frac{15x14x13x12x11}{5x4x3x2xx1}=3,003$
