In the proof that |(0, 1)| > |N|, we use Cantor's Diagonal Method, where we change the nth digit dnn of the nth number r, E (0, 1) in a purported fixed list of all numbers r E (0, 1) by changing dnn to dn = 1 if dnn + 1 and letting dn = 2 otherwise. Then we form a number r* 0.d,d2 ... and claim that because r* is not in the purported list, therefore |(0, 1)| > |N]. State the function used in the proof clearly and, using the definition of two sets being equal in cardinality |A| = |B|, explain why the proof shows that the cardinality of (0, 1) is strictly bigger than the cardinality of N.

10. In the proof that |(0, 1)| > |N, we use Cantor's Diagonal Method, where we change the nth
digit dnn of the nth number rn E (0, 1) in a purported fixed list of all numbers r e (0, 1)
by changing dnn to dm
1 if dnn + 1 and letting dnn
2 otherwise. Then we form a
number r*
0.d d, ... and claim that because r* is not in the purported list, therefore
|(0, 1)| > |N|.
State the function used in the proof clearly and, using the definition of two sets being equal
in cardinality |A| = |B|, explain why the proof shows that the cardinality of (0, 1) is strictly
bigger than the cardinality of N.
