combinatorics – Probability to see at least 2 Elements in Tp 10 of rotating chain?

What is the probability to see at least 2 elements of a certain color in a closed chain (loop) of 100 elements when only 10 successive elements have this certain color? Only the Top 10 elements can be seen and the chain rotates at a constant rate.

Just by counting, I got 17/100 times I see at least two of those elements. How do I calculate it?
