Default symbology when adding new shape

[BeraAkamole]

When i add a new polygon layer to my ArcMap mxd i want the symbol red and 80 % transparency by default and not random color and 0 % transperency.

Is this possible?

The application randomly picks default symbology colors each time you add new data to your map.  You can manually change the symbology through later properties but I don't think you can control what the app picks as a default.  Transparency is something you need to manually set within layer properties.  ArcMap won't automatically set transparency settings.

Anyone else know if its possible?

Python arcpy.mapping could also be used.  Author a layer file (.lyr) and use the UpdateLayer function to apply the symbology in the layer file to the layer of interest.

Jeff's answer is the best option. You could script everything in python and publish a map using parameters etc.

Other then that, the manual route is the only other way.
