The formula below should do what you are after:

=ROWS(FILTER(A2:A, NOT(ISBLANK(A2:A)), NOT(ISBLANK(B2:B))+NOT(ISBLANK(C2:C)) ))

And to explain:

• ROWS counts the rows of the argument (filtered, in our case)
• FILTER returns the rows of arg1 (A2:A) that all subsequent arguments match
• The + (addition) symbol combines two predicates with a logical OR

Finally, if you are not using header columns you can change the references from A2:A to A:A

Alternatively, you can use the QUERY function:

(Broken into multiple lines for readability)

=ROWS(QUERY(A2:C, 
    "SELECT A WHERE A IS NOT NULL AND (B IS NOT NULL OR C IS NOT NULL)"))
