**Problem 1.**

Determine the cardinality of the following sets. For sets which are “uncountably infinite”, indicate so. Support your result with a theorem or formula or diagram.

a) \(\mathfrak{P}(A)\), the power set of \(A\), where \(|A| = 8\)

b) \(\mathbb{N} \times \emptyset\)

c) \(\mathbb{R} - \mathbb{Q}\)

d) \(\{ x \mid 0 < x < 2, \ x \in \mathbb{R} \}\)

e) \(\mathbb{N} \times \mathbb{N}\)
