Assume * E AUB A UB Therefore, we get IE AUB EANB Applying De Morgan's law of proposition, we get - (EA) A-(3 B) Then, we can write z AAB Hence, - (AVX EB) is true Using the definition of the complement of a setre A E B Using the definition of intersection A B NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part Prove De Morgan's law by showing that AU BE A B if A and B are sets. Prove De Morgan's law by showing that each side is a subset of the other side by considering x E AUB Rank the options below
