Question

Question 1 Find the union of each of the following pairs of sets:

(i) X = {1, 3, 5} Y = {1, 2, 3}

(ii) A = {a, e, i, o, u} B = {a, b, c}

(iii) A = {x: x is a natural number and multiple of 3}

B = {x: x is a natural number less than 6}

(iv) A = {x: x is a natural number and 1 < x ≤ 6}

B = {x: x is a natural number and 6 < x < 10}

(v) A = {1, 2, 3}, B = Φ

Answer 1

here is your answer.....

1. X U Y = { 1,2,3,5}
2. A U B = { a,b,c,e,i,o,u}
3. AUB= { 1,2,3,4,5,6,9,12,15,.............}
4. A U B ={2,3,4,5,6,7,8,9}
5. AUB={ 1,2,3}


hope it'll help......
