Question

After the following code executes, what elements will be members of set3? \\[\begin{array}{l}\text { set1 }=\operatorname{set}([10,20,30]) \\\\\text { set2 }=\operatorname{set}([100,200,300]) \\\\\text { set } 3=\text { set } 1 . \text { union (set2) }\end{array}\\]

Short answer

Answer: The elements of set3 are {10, 20, 30, 100, 200, 300}.

Step-by-step solution

Identify the elements in set1 and set2

Set1 has the elements {10, 20, 30} and set2 has the elements {100, 200, 300}.

Perform the union operation

The union operation, denoted by \(𝐴 \bigcup 𝐵\), combines all the elements of sets A and B, without any repetition. Thus, set3 will include all unique elements from both set1 and set2.

Find the elements of set3

By applying the union operation, set3 will include the unique elements from both set1 and set2: {10, 20, 30, 100, 200, 300}.
