Question

01 - Calcule o valor de cada combinação.
a) C5,2
b) C9,8
c) C12,6
d) C14,8​

Answer 1

Resposta:

C5,2 =5!/2!(5-2)!

C5,2=5.4.3!/2.1(3!)

C=10

C9,8= 9!/8!(9-8)!=

C9,8=9.8!/8!=

C=9

C12,6= 12!/6!(12-6)!=

C12,6= 12.11.10.9.8.7.6! /6! (6.5.4.3.2.1)

C12,6=simpl.11.10.9.8.7/5.4.3

C12,6=11.9.8/6=11.9.4/3

11.3.4=132

C14,8=14!/8!(14-8)!

C14,8=14.13.12.11.10.9.8!/8!(6.5.4.3.2.1=

simpl.14.13.11.2.3/.

C14,6=12.012
