A) Universal Set A= {-7, -1,2,8,9,11,13,17,22}
Set B={-1,2,9,11,17}
Set C={-1,8,13,22}
B) are sets B and C subsets of set A ? Explain
Yes......every element of B and/or C is contained in A
C) is set B'= set C ? Explain
No...B' = { −7, 8, 2, 13, 22 } ≠ C
D) find how many elements are in each of the following.
Ï) set B only = 5
Ïï) set C only = 5
Ïïï) set B and set C = 8 [ I'm assuming "and" isn't referring to the intersection of these sets, just to the total number of elements in both sets combined ]
Ïv) set A but not in B or set C = 1
