Best answer
Correct Answer - Option 3 : \(\frac{1}{10}\)

Calculation:

\((1-\frac{1}{2})\)\((1-\frac{1}{3})\).......\((1-\frac{1}{9})\)\((1-\frac{1}{10})\)

⇒ (1 – 1/2) (1 – 1/3) (1 – 1/4) (1 – 1/5).....(1 – 1/9) (1 – 1/10)

⇒ 1/2 × 2/3 × 3/4 × 4/5....8/9 × 9/10

⇒ 1/10

∴ The required value is 1/10
