Calculating FPU using distinct counts

Hi - Here is the table.  What I am looking to calculate is - 

By Week, Month, Qtr and Year

1) Qty of Fails (anything that doesn't have pass in the fault code field)

2) Qty Units that have fails

3) Qty Unit with 0 faults (Any line that has pass in the fault code field)

4) FPU (No of fails/Total Qty Units (qty unit with fails + qty unit with 0 fails))

5) FPY (No of units with 0 fails/Total Qty Units (qty unit with fails + qty unit with 0 fails))

I have a reasonable handle on calculating 1, 2 (using the MO number with a distinct count) and 3 but these are in different visuals.  I am struggling to get it to calculate 4 and 5 as I cant get the DAX code or calculation to add a criteria into my distinct count to only count the MO's with a pass + MO's without stating pass

When I try to do in the same visual the table counts the fail lines as a fail.

I am looking to create a visual that shows the following -
