Could a planet with an atmosphere 10% that of Earth have clouds and precipitation?
If it had liquid water on the surface.

Sure, especially if it had liquid water on the surface, Mars has less than 1% of Earth's atmospheric pressure and it has at least a little precipitation

Yes it could. Mars has clouds, although it doesn't have water snow - but it is cold enough at the poles for the air (mostly CO2) to become dry ice.

Yes. Liquid water is possible down to 1% of our atmospheric pressure although the boiling point in the situation you describe would be very low.
