Thank you for using the site.
The answer for Q1 is b. all results by their probabilities, then summing them up.
I believe that the best answer for Q2 is d. multidimensional. However, this may depend on the particular material that your course is teaching and any unusual definitions or connotations for "static", "dynamic", etc.
If there is anything else that I can help you with, please don't hesitate to ask.
