Kemung~inan terambil 2 kartu

$C presubscript 2 presuperscript 4 equals fraction numerator 4 factorial over denominator left parenthesis 4 minus 2 right parenthesis factorial 2 factorial end fraction equals fraction numerator 4 factorial over denominator 2 factorial 2 factorial end fraction equals fraction numerator 2 factorial cross times 3 cross times 4 over denominator 2 factorial 2 factorial end fraction equals 6$
