comment How many A features that fall both in the B polygons and C polygons are for each C polygon?
I would try to do this using Union (two at a time if you are not using an Advanced level license) followed by Summary Statistics as my basis. Union will write all the overlapping relationships for your input polygon feature classes into a single feature class ready for summarizing. There may need to be a step or two added at the end depending on your precise requirements like totally/partially overlapping, etc.

comment Parameter Not Being Included in Tool
I'm assuming that you are doing this as part of tool validation on a Python script tool rather than in a Python toolbox. If I have misunderstood would you be able to edit your question to clarify that detail, please?

comment Pie Chart Slice Sizing in ArcGIS-Desktop
Are fields a and b meant to be fields 1 and 2? In any event I think the default is that a 50:50 split shows as two equal halves i.e. values are both half the 100 in total. A 50:100 split would show as 33% and 67% i.e. a third and two-thirds of the 150 in total.

comment organizing attribute table: multiple sets of variables per point
Would you be able to ask that as a new question, please? That way it keeps answers closely linked to their corresponding question.

comment organizing attribute table: multiple sets of variables per point
There is a similar question here: gis.stackexchange.com/questions/60868/… I recommend that you look into relates and/or relationship classes.

comment Categorizing polygons instead of using default single symbol in ArcGIS for Desktop?
Can you use the edit button to explain your use case in more detail, please? Is this for when you add a new layer, and open its properties to the symbology tab for the first time?

comment Statistical Analysis using ArcGIS
I think your three questions may be better asked/researched separately as per the "one question per question" of the Tour.

comment Drawing boundary through DEM of glacier valley using ArcGIS for Desktop?
Welcome to GIS SE! You may notice that I have removed your email address from your question. This is because our focussed Q&A format is designed not for one-to-one offline discussion that would help only you, but to act as a learning opportunity for our whole community and any future visitors to our site. To learn more about how GIS SE works I recommend our tour and How to Ask page.

comment Identifying certain polygon from overlapping set
I think your second dot point may be the focus of your question but having that illustrated with a picture would I think make it much clearer. I think the first dot point may be distracting, and making this look harder than it need be, perhaps leave it out, and use for a later question - any answer(s) to this one may make that unnecessary to ask.

comment Software to determine a position within shape
What you are describing sounds like geofencing so that may be a term to search on here and elsewhere.

comment Using Label classes vs Definition queries - which performs the best?
I think "multiple copies of the same layer each with their own definition query and simple field based labeling" will go in as favourite but I have no metrics to back up that gut feeling so I think this is a great question. Would a file geodatabase feature class with one million polygons qualify as a very large dataset in your parlance?

comment Project Point using ArcGIS API for JavaScript?
That's no problem. A title is never wrong but I think some titles can attract potential answerers to your question better than others - this Meta Q&A describes what we think and have found works best in more detail.

comment Exporting layout elements and constants to Python script?
@JoeBird I'm not aware of any available "Export Layout to ArcPy" script that could read a template MXD and write runnable code to configure another MXD, and to try and write one seems overkill for what you describe. I think you need to break your requirements down into a series of discrete tasks and once you know how to achieve each, then stringing them together becomes much easier. How to do each of these discrete tasks could be researched/asked separately here but answering your current question with code to do it all is too broad for our focussed Q&A format.

comment mxd.saveACopy(outMxd) not working
Sounds like just keeping an eye out for any pattern of fails vs works may be all you can do for now. In particular keep an eye on whether there is any remote possibility that another window/process may be holding a lock on the file you are trying to write to.

comment Calculating area of larger polygon containing smaller polygon of same feature class inside it using ArcGIS for Desktop?
Would you be able to edit your question (there is an edit button beneath it) to explain whether you are using a geodatabase or map topology, please? If it is neither, can you provide more details about whether you perhaps just have one soil type polygon sitting on top of a larger one and you want the smaller one to "cut through" the larger one, please?

comment mxd.saveACopy(outMxd) not working
You say it is an "an intermittent error" but do you mean intermittent in terms of different pathnames, or does even the one pathname you give in your example work sometimes and not others?

comment Preventing ArcPy from changing MXD extent?
If you code in ArcObjects then that is an option but not one I can help with.

comment Preventing ArcPy from changing MXD extent?
If it is a bug then I can think of no workaround to it. I'm assuming that you are actually using ArcGIS Desktop 10.0 SP5. If not, I recommend upgrading to at least that.
