[tex]\bf ^{6}P_{2}[/tex] = ...
Jawaban:
[tex] [/tex]
[tex] \sf= \: ^{6}P_{2}[/tex]
[tex] \sf = \frac{6!}{(6 - 2)!} [/tex]
[tex] \sf= \frac{6!}{4!} [/tex]
[tex] = \frac{6 \times 5 \times 4!}{4!} [/tex]
[tex] = 6 \times 5[/tex]
[tex] = 30[/tex]
Permutasi
[tex]\bf ^{n}P_{r} = \frac{n!}{(n - r)!} [/tex]
[tex]\bf ^{6}P_{2} = \frac{6!}{(6 - 2)!} [/tex]
[tex] \sf = \frac{6!}{4!} [/tex]
[tex] \sf = \frac{6 \times 5 \times 4!}{4!} [/tex]
[tex] \sf = \frac{6 \times 5 \times \cancel{ 4!}}{ \cancel{4!} }[/tex]
= 6 × 5
= 30
