Answer 1

You can use a single formula like this:

=SUM(IF(FREQUENCY(IF(A2:A200="John",IF(C2:C200="No",B2:B200)),B2:B200),1))

That's an "array formula that needs to be confirmed with CTRL+SHIFT+ENTER

That gives 3 for your example - note that it requires column B data to be numeric which seems to be the case here.....
