hi anyone here please answer my question please
Explanation:
4. Let A = {x : x is a multiple of 2 , x < 15),
B = {x : x is a multiple of 3, x < 20),
C = {x : x is a prime, x < 20}.
Write each one of the sets A, B, C in Roster form.
(i) write each one of the sets A,B,C in roster form
(ii) Find :
(a) A U B
(b) A U C
(c) B u c
(d) A ∩ b
(e) A ∩ b
(f) В ∩ c
6. Let A = {2, 4, 6, 8), B = {6, 8, 10, 12} and C = {7, 8, 9, 10}. Find :
(i) A U B
(ii) A U C
(iii)B U C
(IV) A ∩ B
(V) A ∩ C
(vi) B ∩ C
3. Write each of the following sets in Roster form and write the cardinal number of each
(i) A = {x : x is an integer, -3 < x < 4}.
(ii) B = {x: 6 N, 3x - 6 < 9}.
(iii) C = {x : x = n2, n e N, 10 <n < 16).
(iv) D = {x:x = W, x - 3 < 2}.
(v) E= {r : x = 2n -1,n e N and n < 6}.
(vi) F = {x : x is a letter in the word 'COMMON'}.
(vii) G = {x: x is a primary colour}.
(viii) H = {x : x is a digit in the numeral 2362).
(ix) J = {x: x = 1/n e N, 4 <n<10}
4. Write each of the following sets in set-builder form :
(i) A = {4, 6, 8, 9, 10, 12, 14, 15, 16, 18).
(ii) B = {1, 2, 3, 5, 6, 10, 15, 30).
(iii) C = {-9, -6, -3, 0, 3, 6, 9, 12, 15).
1 2 3
8
(iv) D= {1/2, 2/3, 3/4, 4/5, 5/6, 6/7, 7/8, 8/9}
(V) E = {1/3, 1/5, 1/7, 1/11 ,1/13, 1/17, 1/19}
(vi) F = {April, June, September, November{
(vii) G = {0}.
(viii) H = { ).
6. Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10) be the universal set and let
A = {2, 3, 4, 5, 6} and B = {3, 5, 7, 8) be its subsets.
(1) A
Verify that: (v) (A U B)' = (A' B')
Find :
(i) A'
(ii) B'
(iii) A' ∩ B'
(iv) A' U B'
(v) ( A U B)' = (A ∩ B)'
(vi) (A ∩ B)' = (A' U B')
7. Let U = {a, b, c, d, e, f, g} be the universal set and let its subsets be
A = {a, b, d, e} and B = {b, e,g}.
Verify that : (i) (A U B)' = (A' B')
(ii) (A i B)' = (A'U B')
8. Let U = {3, 6, 9, 12, 15, 18, 21, 24} be the universal set and let
A = {6, 12, 18, 24} be its subset.
Verify that :
(i) A U A = A
(ii) A ∩ A = A
(iii) A ∩ A' = ∅
(iv) AU A' = U
(v) (A)' = A
please answer this correctly please
