KOMBINASI

KOMBINASI adalah suatu pengacakan dengan tidak memperhatikan urutan.

contoh ::

H={a1, a2, a3}

Dibentuk kombinasi 2 dari H diperoleh : H1={(a1, a2), (a1, a3), (a2, a3)}

Lambang H1 =( H2 )

n(H1)=n( H2 )=3

n(H) = 3 → n(H1) = ( 32 )=3

Hubungan permutasi dan kombinasi :

KOMBINASI

PERMUTASI

( 22 )=1

P(2,2)=2

 ( 32 )=3

 P(2,3)=6

 ( 43 )=4

 P(3,4)=24

 …

 …

 …

 …

( nr ) 

 P(r,n)=r!( nr )

Dengan demikian, P(r,n)=r!( nr ) dapat kita ubah menjadi :

( nr ) = P(r,n)/r! = n!/(n-r)! . 1/r! = n!/r!(n-r)!
