I don't know about the U.K. but in Germany probability theory, even at the senior level, hardly consisted of more than combinatorics, which is probably the worst way to teach probability. Only nowadays curricula are slowly catching up.

I wouldn't know either. My math teachers advised me to give it up at 16 and I took their advice.

I found it a little depressing that what students in Germany learn about probability theory in the Abitur culminates in NHST, at a moment when we have everything there to put that behind us.
