How to evaluate the following sum?

$\frac{100}{100}\cdot 1+\frac{100\cdot 99}{{100}^{2}}\cdot 2+\frac{100\cdot 99\cdot 98}{{100}^{3}}\cdot 3+\frac{100\cdot 99\cdot 98\cdot 97}{{100}^{4}}\cdot 4+\dots +\frac{100\cdot 99\cdot 98\cdot \dots \cdot 1}{{100}^{100}}$

What I have tried:

Above sum can be written as $S=\sum _{i=1}^{100}\frac{100\cdot 99\cdot ...\cdot (100-i+1)}{{100}^{i}}\cdot i$

$=\sum _{i=1}^{100}\frac{{}^{100}{P}_{i}}{{100}^{i}}\cdot i$

When you are dealing with statistics and probability as a college student, you should focus on the differences between quantitative data examples and connect questions with the answers. Take your time to study equations and link them to quantitative data questions as it will help you choose the most suitable method of this mathematical branch. If you feel confused, think about reverse-engineering the problem that you may have and it will make you see how certain solutions can be brought back to the original equation. See available examples and proceed from there to get the best results.
