4. If U = {x: 2
prime number} then find the following:

(i) AOB
5. IfA = {1, 3, 5) B = {2,4,6,8), C = {2, 5, 10) and U = {1, 2, 3, 4, 5, 6
9, 10}. Verify that.
a) (An B) = ĀUB
b) An(BUC) = (

c) AN(B-C) = (ANB)-(ANC) d) An(BOC)= (ANB) nc ·
e) A-B=AB
(f) A = A.
6. Given A={1,2,3), B={3,4,5) and U = {1,2,3,4,5,6), verify that (AUB) = An.

7. List all the subsets of the set A = {-1, 0, 1}. Hence find power set of A. i.
8. Let U = {x: x < 5, xe Z}, A = {x: x + x² - 2x = 0; and
B = {x:x is even integer}. Find A-B and B-A. Are B-A and A - B same
9. Let A= {a, b} and B = {a, b,c}. Is ACB? Find AUB?

the correct answers i think are b. and d.

give me brainliest if it is correct!

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
