Hi all!(adsbygoogle = window.adsbygoogle || []).push({});

I'm in serious need of some help.

The question:

How many binary strings of length 10 contains exactly two "01"?

My idea was to weld together 4 bits to 2 "01". That way, there's [tex]\frac{8!}{2!}[/tex] strings withat least2 "01". But there are a bunch of strings with more than 2 "01" in these, and these must be accounted for. How can I locate these?

Thanks in advance,

Nille
