Have you ever wondered about how many prime numbers may exist?

Well, I guess you haven't, but if you'd like to find out, you should visit a maths classic: The Prime Number Shitting Bear

NEW CHALLENGE

Let's finish this "numbers" units with this short challenge:

Can you find out the final result of the following opeartion?
$$\left(1-\frac{1}{2} \right) \cdot \left(1-\frac{1}{3} \right) \cdot \left(1-\frac{1}{4} \right) \cdots \left(1-\frac{1}{999} \right) \cdot \left(1-\frac{1}{1000} \right)$$
