Answer:
5. TOTAL NUMBER OF SUBSETS: (i think u need another set)
CARDINALITY: 7
6. TOTAL NUMBERS OF SUBSETS: (i think u need another set)
CARDINALITY: 8
Step-by-step explanation:
WHAT IS SUBSET?
In mathematics, a 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.
WHAT IS CARDINALITY?
The cardinality of a set is a measure of a set's size, meaning the number of elements in the set. For instance, the set A = { 1 , 2 , 4 } A = \{1,2,4\} A={1,2,4} has a cardinality of 3 for the three elements that are in it.
(IN MY OWN UNDERSTANDING ABOUT CARDINALITY, IT WAS ABOUT THE NUMBER OF ELEMENTS IN A SET FOR EXAMPLE; A={1,2,3} IT HAS 3 ELEMENTS SO THE CARDINALITY IS 3)
(AND IN MY OWN UNDERSTANDING ABOUT SUBSET, IT WAS LIKE FOR EXAMPLE; SET A= {1,2,3,4,5} SET B= {1,2,3} U CAN SEE THAT SET A CONTAINS ALL ELEMENTS IN SET B, SO THE PROPER SUBSET OF SET B IS SET A}
