Help with Message to Filter Distinct Count



I am looking to calculate the number of agents that worked on a ticket each month to ascertain the average number of tickets per agent. I have two measures:


Agents Available per Month = CALCULATE(DISTINCTCOUNT('Cases'[Resolved By]),ALLSELECTED('Cases'[Case Number]))
Average Assigned Tickets per Agent = DIVIDE(DISTINCTCOUNT('Cases'[Case Number]),[Agents Available per Month])
I wish to filter out any rogue cases when an Agent has resolved <10 tickets within the month however I am unsure what is missing from the first measure to achieve this. I have tried:
Agents Available per Month = CALCULATE(DISTINCTCOUNT('Cases'[Resolved By]),ALLSELECTED('Cases'[Case Number]),COUNT('Cases'[Resolved By])<=10)
But no luck.
Many thanks in advanced
