then
power set
А "6​

Answer 1

Answer:

All sets are proper subsets except the set that contains all of the elements. The number of subsets is always 2^n where n is the number of elements in the set; in this case 5. There should be 2^5=32 subsets including the empty set and the set itself.

All the subsets are: {}, {3}, {6}, {9}, {12}, {3,6}, {3,9}, {3,12}, {6,9}, {6,12}, {9,12}, {3,6,9}, {3,6,12}, {3,9,12}, {6,9,12} and {3,6,9,12}. Note: {} is a null/empty set and it is a subset of any given set.
