Question

7.
Let U = {1, 2, 3, 4, 5,6,7,8,9,10,11,12,13,14,15} ;
A= {2, , 3, 4, 6, 7, 8} ; B = {2, 3, 5, 7, 11, 13, 17}
Find
(i) A n B
(ii) (A U B)'
(iii) B - A
(iv) A'​

Answer 1

Step-by-step explanation:

(i) (AnB) = {2,3,7}

(ii) (AUB)' = first find the values of (AUB)

(AUB)= {2,3,4,5,6,7,8,13,17}

now the complement of this is:-

(AUB)' = {1,9,10,11,12,14,15}

(iii) (B - A) = {5,11,13,17}

(iv) (A)' = {1,5,9,10,11,12,13,14,15}

Hope you found this answer helpful.
