Check out the XL help file article:
"Count unique values among duplicates "

You can do this via filters or functions, your choice. For your example, it
looks like you will need something like:
=SUM(IF(FREQUENCY(IF(LEN(A2:A10)0,MATCH(A2:A10,A2 :A10,0),""),
IF(LEN(A2:A10)0,MATCH(A2:A10,A2:A10,0),""))0,1))

Note that this is an array formula, and must be confirmed using
Ctrl+Shift+Enter, not just Enter.

Use the following array formula:
=sum(1/Countif(RangeOfCells,RangeOfCells))

confirm the formula with Ctrl +Shift+Enter instead of just the Enter key
