a) Which of the following statements are true? Briefly justify your answer (one liner). {{ø}} ⊂ {{ø}, {ø}} {ø} ∈ {ø, {ø, 0}} b) What is the cardinality of the set {ø, {ø}, {ø, {ø}}, {ø}}? c) Write the power set of {ø, {a}, {ø, a}}.

Step 1
{{ø}} ⊂ {{ø}, {ø}}: This statement is true because the set {ø} is a subset of the set {{ø}, {ø}} since it contains all the elements of {ø}. Show more…
