1 : a set each of whose elements is an element of an inclusive set. 2 : division, portion a subset of our community.
Step-by-step explanation:
In mathematics, set A is a subset of a set B if all elements of A are also elements of B; B is then a superset of A. It is possible for A and B to be equal; if they are unequal, then A is a proper subset of B. The relationship of one set being a subset of another is called inclusion
For this problem, it is really important to find who voted on Tuesday first. 90×(3/5)= 54 54 people voted on Tuesday. Since the people who voted on Wednesday was 1/4 of the members who did not vote on Tuesday. 90-54=36×(1/4)=9 9 people voted on Wednesday. Now add Tuesday and Wednesday together to find the ones that didn't vote. 54+9=63;90-63=27 27 people did not vote at all.
