The diagram shows the number of children who have ever used motorized scooters, manual scooters, and/or bicycles.

which combination represents the empty set?

motor ⋃ manual
motor ⋃ bicycle
motor ∩ manual
motor ∩ bicycle

ANSWER

motor ∩ bicycle

EXPLANATION

The ∩ symbol represents the intersection, that is, A ∩ B is the set containing the elements that are in BOTH A and B.

motor ∩ bicycle means the intersection of two sets: motor and bicycle.

The intersection motor ∩ bicycle is a set that contains all elements that are in the motor set that are also in the bicycle set.

According to the Venn diagram, there are no items in the motor set that are also in the bicycle set. (If there were common elements to both sets, then there would be a Venn diagram overlap)

Therefore, motor ∩ bicycle = ∅, where ∅ is the empty set
