DAX Sum two columns, divide by a third column, and total based on a list of constants

[Anonymous]

Hey everyone,

I am very new to DAX functions and am having a hard time calulating a percentage. I would like to create a new column that contains the total percentage for a group of people. 

To find the percentage I have to add the values from two columns together and divide by the values in a third column. I also need to total that percentage based on a group of people. 

Thanks!

@Anonymous , It should work like

Divide(Sum(Table[Col1]) + Sum(Table[Col2]) , Sum(Table[Col3]) )

or

Divide(SumX(table, Table[Col1]+Table[Col2]) , Sum(Table[Col3]) )
