Full solution

Q. Let A={1,2,3}A = \{1, 2, 3\} and B={2,4}B = \{2, 4\}. What is A∪BA \cup B?\newlineChoices:\newline(A){1,3,4}\{1, 3, 4\}\newline(B){1,2,3,4}\{1, 2, 3, 4\}\newline(C){2}\{2\}\newline(D){4}\{4\}
  1. Identify Sets A and B: Identify the elements of set A and set B.\newlineSet A = 1,2,3{1, 2, 3}\newlineSet B = 2,4{2, 4}
  2. Combine Unique Elements: Combine all unique elements from both sets to form the union.\newlineThe union of two sets, denoted by A∪BA \cup B, includes all the elements that are in AA, or in BB, or in both. \newlineA∪B={1,2,3,4}A \cup B = \{1, 2, 3, 4\}
  3. Check Answer: Check the answer against the provided choices.\newlineThe correct answer is (B)1,2,3,4{1, 2, 3, 4}, which matches our calculated union of sets AA and BB.
