If A = {1, 2, 3, 4} and B = {3, 4, 5, 6}, Which of the following is true?
ক)
A ∪ B = {1, 2, 3, 4, 5, 6}খ)
A ∩ B = {3, 4}গ)
A - B = {1, 2}ঘ)
All of the aboveExplanation
The symbols ∪, ∩, and - refer to the set operations union, intersection, and set difference, respectively. The union of two sets A and B (denoted by A ∪ B) is the set of elements that are in A, or in B, or in both. So, A ∪ B is {1, 2, 3, 4, 5, 6}. The intersection of two sets A and B (denoted by A ∩ B) is the set of elements that are in both A and B. So, A ∩ B is {3, 4}. The set difference of A and B (denoted by A - B) is the set of elements that are in A but not in B. So, A - B is {1, 2}.Related questions
