Suppose that you had infinitely many people, each one wearing a uniquely numbered button: 1, 2, 3, 4, 5, .... You also have lots of pennies. You give each person a penny; then ask everyone to flip his or her penny at the same time. Then you ask them to shout out in order what they flipped (H for heads and T for tails). So you might hear: HHTHHTTТТHTTHTHТHTHHНННТН... or THTTTTHTHHHTTHTHTHTTTTTHHT... and so forth. Consider the set of all possible outcomes of their flipping (all possible sequences of H's and T's). Does the set of possible outcomes have the same cardinality as the natural numbers? Justify your answer.

Question
Suppose that you had infinitely many people, each one wearing a uniquely numbered
button: 1, 2, 3, 4, 5, .... You also have lots of pennies. You give each person a penny;
then ask everyone to flip his or her penny at the same time. Then you ask them to shout out
in order what they flipped (H for heads and T for tails). So you might hear:
HHTHHTTТТHTTHTHТHTHHНННТН... or
THTTTTHTHHHTTHTHTHTTTTTHHT... and so forth.
Consider the set of all possible outcomes of their flipping (all possible sequences of H's and
T's). Does the set of possible outcomes have the same cardinality as the natural numbers?
Justify your answer.
