Explicação passo-a-passo:
[tex]\mathsf{C_{n,p} = \dfrac{n!}{p!(n - p)!}}[/tex]
[tex]\mathsf{C_{6,3} \times C_{12,8} = \dfrac{6!}{3!(6 - 3)!} \times \dfrac{12!}{8!(12 - 8)!}}[/tex]
[tex]\mathsf{C_{6,3} \times C_{12,8} = \dfrac{6!}{3!.3!} \times \dfrac{12!}{8!.4!}}[/tex]
[tex]\mathsf{C_{6,3} \times C_{12,8} = 20 \times 495}[/tex]
[tex]\boxed{\boxed{\mathsf{C_{6,3} \times C_{12,8} = 9.900}}}[/tex]
