Total count of two different content types in one View?
The table in the screen capture is similar to this one:



The Views Calc module can be used to transform that table so that the calculations in the last rows (with Count, Sum and Max) get added to it.

By replacing the columns like '# Fish' and 'Weight' with 'Total Demonstrations' and 'Total deliverable ...' (as in the question), and by asking for only the 'sum' to be added, it should answer the question.

To ask for the 'sum', just select it from the selection list, similar to what is shown in this screenshot:



For more details (step-by-step instructions), refer to the community documentation about the Views Calc module.
