pick the numbers that are in BOTH sets

anonymous · Answer

find the numbers that are common to A∩B , this is where a and b intersect

anonymous · Answer

would the answer be a? because those numbers are in both sets A & B ?

anonymous · Answer

no it would be B!!

anonymous · Answer

why b?You were right with your first answer
