Which of the following are correct statements? A = {1, 2, 3, 4, 5, 6}
(a) {2, 3} ⊂ A
(b) {1, 2, 3, 4, 5,6, 7} ⊃ A
(c) 8 ⊂ A
(d) {3, 5, 1, 7} ⊃ A
(e) {1} ⊂ A
(f) {1, 2, 3, 4} ⊂ A
(g) { } ⊃ A
(h) ϕ ⊂ A
If A = {3,6,9,12,15,18,21}, B= {}, B= {3,6,9}, C= {9,12}, and D = {3,12,21}, then complete each of the following statements:
(a) B ⊂ A { } ⊂ { }
(b) C ⊂ A { } ⊂ { }
(c) D ⊂ A { } ⊂ { }
(d) C ⊄ B { } ⊂ { }
Give that set P = { 2,4,6,8} calculate the number of possible subsets of P (2pts)
If A = {2,4}, B = {2,4,6,8} and C = {2,4,6,8,10,12,14} state where the state A⊂ B⊂C is true or false. (2pts)
Give the set {1,2,4,5,7,8,10,11,19,22,35,39,41,54} state the numbers which is (are):
(a) Prime
(b) Even
(c) Multiples of 3
(d) Odd
(e) Multiple of 2
