WebExplanation: The union set contains the elements of both set A and set B and It is denoted by A ∪ B. The formula for A ∪ B is {x: x ∈ A (or) x ∈ B} Let's see an example. Find the union set of set A = {1, 2, 3, 4} and set B = {4, 5, 6}. Here elements of A are 1, 2, 3, 4 and the elements of B are 4, 5 , 6 Hence the elements of the union set be WebUnion, Intersection, and Complement. The union of two sets contains all the elements contained in either set (or both sets). The union is notated A ⋃ B. More formally, x ∊ A ⋃ B if x ∈ A or x ∈ B (or both) The intersection of two sets contains only the elements that are in both sets. The intersection is notated A ⋂ B. More formally, x ∈ A ⋂ B if x ∈ A and x ∈ B. recover data from cracked sd card
