Question

Consider the following statements:

 

(1) (√2·√6) / (√18-√24) is an irrational number. (2) Let S = Ø x A. Then, | P(S) |= 0, where P(S) denotes the power set and | | denotes cardinality (that is, the number of elements). (3) If n is a positive integer, then n is odd if and only if 5n + 6 is odd. Select one of the following choices: (a) (2) and (3) are True, (1) is False. (c) (1) and (2) are False, (3) is True. (b) (1) and (2) are True, (3) is False. (d) (1) and (3) are True, (2) is False.
