Answer:
1.AUB = False
2. False
3. False
Explanation:
Given the data below:
A = {4, 7, 10, 13, 17)
B = {3,5,7,9)
1) AUB = {3,4,5,7,9,10,13,17}
2) B⊂B means B is a subset of , with every element in B present in B. However, the second se has more element.
(3,5,7,9) ⊆ (3,5,7,9)
3.) BCA. A is a subset of B
All elements of B is in a A
False - there are elements in B that are not in A
