Q. Let M={6,9,12}M = \{6, 9, 12\} and N={4,6,7,9,12,15}N = \{4, 6, 7, 9, 12, 15\}. What is M∩NM \cap N?\newlineChoices:\newline(A){4,6,7,9,12,15}\{4, 6, 7, 9, 12, 15\}\newline(B){6,9}\{6, 9\}\newline(C){6,9,12}\{6, 9, 12\}\newline(D){6,7,12,15}\{6, 7, 12, 15\}
  1. Identify Common Elements: To find the intersection of two sets, we need to identify the elements that are common to both sets. The intersection is denoted by M∩NM \cap N.
  2. List Elements of Sets: List the elements of set MM: M={6,9,12}M = \{6, 9, 12\}. List the elements of set NN: N={4,6,7,9,12,15}N = \{4, 6, 7, 9, 12, 15\}.
  3. Compare Elements: Compare the elements of set MM with the elements of set NN to find the common elements.\newlineThe common elements are 66, 99, and 1212.
  4. Find Intersection: The intersection of sets MM and NN, M∩NM \cap N, is the set of elements that are in both MM and NN. Therefore, M∩N={6,9,12}M \cap N = \{6, 9, 12\}.
