The mutation rates for these markers are not well known, but they are
evidently quite high. You really cannot build anything on the
particular values you see.

It's not at all clear what you mean by a "combined percentage probability"
or how you would go about calculating it. I hope you understand that
linkage disequilibrium always applies to Y DNA markers.
