you can do that with a measure that uses VALUES, SELECTCOLUMNS and SUMX.  But it will be expensive as you will have to recalculate the SUMX for each individual "row".  How big is your dataset?

 

For Bayes you need to have knowledge of a prior event. What is that - the probability for the previous month?

    Thanks ibendlin for your time.

     

    Size of dataset is roughly 5000 rows and growing. 

    For 2nd question, as you suggested, the previous month probability is available.

      Give it a try - worst case you can use R or Python Script instead.
