Hitunglah Hasil (1 - 1/2) (1 -1/3) (1 -1/4) (1 -1/5)

[tex](1- \frac{1}{2} )*(1- \frac{1}{3} )*(1- \frac{1}{4} )*(1- \frac{1}{5} )= \frac{1}{2} *\frac{2}{3} *\frac{3}{4} *\frac{4}{5}=\frac{1}{5} [/tex].

Kerjakan yang berada di dalam kurung terlebih dahulu.

(1 - 1/2) (1 - 1/3) (1 - 1/4) (1 - 1/5) =
(2/2 - 1/2) (3/3 - 1/3) (4/4 - 1/4) (5/5 - 1/5) =
(1/2) (2/3) (3/4) (4/5) =
(1 x 2 x 3 x 4) / (2 x 3 x 4 x 5) =
24 / 120 =
0,2

semoga membantu:)
