Table schema:
CREATE TABLE table_name_63 (plaxo INTEGER, friendster VARCHAR, myspace VARCHAR, bebo VARCHAR)

Question: What is the average plaxo that has a myspace greater than 64, a bebo greater than 3, with 4 as the friendster?
SQL: SELECT AVG(plaxo) FROM table_name_63 WHERE myspace > 64 AND bebo > 3 AND friendster = 4
