Check all true statements. Group of answer choices If A={1,2} and B={3} then A x B ={ (1,3), (2,3) }. For all sets A, B, the cardinality of A x B is the sum of the cardinalities of A and B. If A={1,2} and B={3} then A x B ={ {1,3}, {2,3} }. The cartesian product has a cancellation property, i. e. if A x B = A x C for some sets A, B, C and A nonempty, then B = C. For all sets A, B, the power set of the cartesian product of A and B is the cartesian product of the power sets of A and B. The cartesian product is symmetric, i. e. A x B = B x A for all sets A, B.
