Question

qual o valor de c6,5 e o valor de C4,3

Answer 1

$C_{n,p} = \frac{n!}{p!(n-p)!} \\C_{6,5} = \frac{6!}{5!(6-5)!} \\C_{6,5} = \frac{6!}{5!(1)!} \\C_{6,5} = \frac{6!}{5!} \\C_{6,5} = \frac{6 * 5!}{5!} \\C_{6,5} = 6$

$C_{n,p} = \frac{n!}{p!(n-p)!} \\C_{4,3} = \frac{4!}{3!(4-3)!} \\C_{4,3} = \frac{4!}{3!(1)!} \\C_{4,3} = \frac{4!}{3!} \\C_{4,3} = \frac{4 * 3!}{3!} \\C_{4,3} = 4$
