Explicação passo a passo:
[tex]\mathsf{C = \dfrac{n!}{p!.(n - p)!}}[/tex]
[tex]\mathsf{C_{16,2} - C_{4,2} = \dfrac{16!}{2!.(16-2)!} - \dfrac{4!}{2!.(4-2)!}}[/tex]
[tex]\mathsf{C_{16,2} - C_{4,2} = \dfrac{16.15.14!}{2!.14!} - \dfrac{4.3.2!}{2!.2!}}[/tex]
[tex]\mathsf{C_{16,2} - C_{4,2} = \dfrac{240}{2} - \dfrac{12}{2}}[/tex]
[tex]\mathsf{C_{16,2} - C_{4,2} = 120 - 6}[/tex]
[tex]\boxed{\boxed{\mathsf{C_{16,2} - C_{4,2} = 114}}}[/tex]
