Number of occurences in a column

Hello ! 

I'm trying to fill a Card Box in Power BI with the differents occurences of words in my column

I have a column (NumberTel) that count the number of phone I have in my table (0, 1, 2, 3) and I would like to know how to put (in percent) those values in a Visual element

I know how to make a graph (doughnut / circular /etc.) but I would like to put them in a Card box 

I know the syntax of this query in SQLServer but can't figure out how to do it in PowerBI...

I don't want to create 4 columns for my 4 values with 1 or 0 in it and them sum it to have the amount of each one (Already had this idea but not the best option)

Thanks in advance
