There are 8 leaves in the universal set, 6 leaves in the shaded subset and 2 leaves in the not-shaded subset. This can be obtained by understanding what a set, universal set and subset is.
What is a set?
- Set is a collection of well defined objects.
- For example, set of months in a year.
What is a universal set?
- Universal set is the set of all elements that is discussed in the question.
- For example, if A = {2,3,5}, B = {1,4,5}, Universal set U = {1,2,3,4,5}
What is subset?
- A is a subset of B is all elements of A is present in set B.
- For example, A = {1,2}, B = {1,2,3,4,5} then A is a subset of B.
Thus in the universal set there are 8 leaves, in the shaded subset there are 6 leaves and in the not-shaded subset there are 2 leaves.
