Question

The set S represents the elements present in sugar.

S = {carbon, hydrogen, oxygen}

The set C represents the elements present in carbon dioxide gas.

C = {carbon, oxygen}

How many elements are in the set S ∩ C?

Answer 1

The intersection has a cardinality of 2, i.e. it contains two elements -- carbon and oxygen, those which are in common.

Answer 2

so its 2?

Answer 3

2

Answer 4

yeah 2 since they both have carbon and oxygen and intersection means those they both have :)

Answer 5

At an auto show, a car dealer asked the first 10 visitors their ages and the kinds of cars they own. The Venn diagram shows the details.

Answer 6

Based on the diagram, which of the following represents the ages of car owners in the set
