Count posts in taxonomy with specific meta value

Hello!
I have ten custom post terms (t1-t10 for easy understanding). Posts inside those terms have same meta_key (let’s say example_key), which differs in meta_value (let’s say value is ‘free’).

I’d like to print count of that posts, so I have something like:
t1: 10 Free
t2: 14 Free
etc.

Any fast&easy way to do that? 🙂
thanks!
