A. 1.225
Penjelasan dengan langkah-langkah:
KOMBINASI
n = 50
r = 2
nCr = n!
(n–r)!r!
50C2 = 50!
(50–2)!2!
50C2 = 50×49×48!
2 × 1 × 48!
50C2 = 50 × 49
2
50C2 = 2.450
nCr = n! / ( n - r )! . r!
50C2 = 50! / (50-2)! . 2!
50C2 = ( 50.49.48 ) / 48! . ( 2.1 )
50C2 = 50×49 / 2
50C2 = 2.450/2
50C2 = 1.225 ( Opsi a )
