Group columns based on number of value in a table

[#1]

I have this table with three columns (dut, vcc, result) (for exemple) :

dut | vcc | result | 
1    | 1.1 | pass
2    | 1.1 | pass
3    | 1.1 | pass
4    | 1.1 | pass
1    | 1.2 | pass
2    | 1.2 | fail
3    | 1.2 | pass
4    | 1.2 | pass
1    | 1.3 | pass
2    | 1.3 | fail
3    | 1.3 | fail
4    | 1.3 | fail

And I want to group by vcc the number of pass so have this table :

vcc | number | 
1.1 | 4
1.2 | 3
1.3 | 1

 What are the easiest ways to move from the first table to the other ?

Using Tabulate or Summary. With summary you can get something like this:

and tabulate

do note that vcc should be Nominal column
