The answer to exercises marked [BB] can be found in the Back of the Book.
Determine, with justification, whether each of the following sets is finite, countably infinite, or uncountable.
(a) [BB] {x ∈ R | 1 < x < 2}
(b) {x ∈ Q| 1 < x < 2}
(c)
(d)
(e) [BB] [a+bi ∈ C |a, b ∈ N}
(f) {(a, b)∈ Q × Q| a +b = 1}
(g)
