\(C=\left(1-\frac{1}{2}\right)\cdot\left(1-\frac{1}{3}\right)\cdot\left(1-\frac{1}{4}\right)\cdot...\cdot\left(1-\frac{1}{2017}\right)\cdot\left(1-\frac{1}{2018}\right)\)
\(C=\frac{1}{2}\cdot\frac{2}{3}\cdot\frac{3}{4}\cdot...\cdot\frac{2016}{2017}\cdot\frac{2017}{2018}\)
\(C=\frac{1\cdot2\cdot3\cdot...\cdot2016\cdot2017}{2\cdot3\cdot4\cdot...\cdot2017\cdot2018}\)
\(C=\frac{1}{2018}\)
