(1 - 1/97) .(1 - 1/98)....(1 - 1/1000)

= (97/97 - 1/97).(98/98 - 1/98) ... (1000/1000 - 1/1000)

= 96/97 . 97/98....999/1000

= 96.97....999/97.98.....1000

= 96/1000

= 12/125

\((1-\frac{1}{97})\cdot(1-\frac{1}{98})\cdot...\cdot(1-\frac{1}{1000})\)

\(=(\frac{97}{97}-\frac{1}{97})(\frac{98}{98}-\frac{1}{98})....(\frac{1000}{1000}-\frac{1}{1000})\)

\(=\frac{96}{97}\cdot\frac{97}{98}\cdot...\cdot\frac{999}{1000}\)

\(=\frac{96}{1000}\)

\(=\frac{12}{125}\)
