Power BI Case Study $-$ Question $2/4$

Expand the Filtered Context of a DAX Measure

The $$Total Average Balance$$ column in the Task $2$ visual is currently displaying the same results as the $$Average Balance$$ column. You need to update the $$Total Average Balance$$ measure to return the Average Balance for the entire dataset in each row of the Task $2$ table.

Which DAX function can you use as the second argument in CALCULATE$()$ to achieve this task?
