\(\left(1-\frac{1}{97}\right)\times\left(1-\frac{1}{98}\right)\times...\times\left(1-\frac{1}{1000}\right)\)
\(=\frac{96}{97}\times\frac{97}{98}\times...\times\frac{999}{1000}\)
\(=\frac{96\times97\times...\times999}{97\times98\times...\times1000}\)
\(=\frac{96}{1000}\)
\(=\frac{12}{125}\)
_Chúc bạn học tốt_
\(\left(1-\frac{1}{97}\right)\cdot\left(1-\frac{1}{98}\right)\cdot...\cdot\left(1-\frac{1}{1000}\right)\)
\(=\frac{96}{97}\cdot\frac{97}{98}\cdot...\cdot\frac{99}{1000}\)
\(=\frac{96}{1000}=\frac{12}{125}\)
