count of distinct two columns in one table

Hi all, 
I am trying to calculation the unique number of users who did 2 or more activities from two separate columns in one table. 
My data looks like this: 

 

Table  

 

user_idactivity_id
1aa
2aa2
3aa3
4aa4
5aa5


First I want to get the distinct count of users and then filter those users that have done 2 or more activities.
I am trying something like this, but I am not getting the values right. 

VAR allData =
ADDCOLUMNS(
VALUES(Table[activity_id]),
"rowCount",
CALCULATE( COUNTROWS( Table) )
)
return
CALCULATE(
COUNTROWS( allData ),
filter (allData, [rowCount] >=7)
)

 

 

I appreciate all the help.

@91asma2 , Try a measure like

 

countx(filter(summarize(Table, Table[user_id], "_1", count(Table[activity_id])),[_1]>=2),[user_id])

Thanks a lot @amitchandak !

I am trying to validate the values. and I am trying to change the filter from 2 to 1 to 3 ...etc but the number doesnt change. 

so I am not sure its counting the right values.
