Consider the following ORACLE relations: One (x, y) = {<2, 5>, <1, 6>, <1, 6>, <1, 6>, <4, 8>, <4, 8>} Two (x, y) = {<2, 55>, <1, 1>, <4, 4>, <1, 6>, <4, ... EXCEPT ALL (SELECT * FROM Two); For each of the SQL queries, what is the cardinality (number of rows) of the result obtained when applied to the instances above ?
