Question

1. If A = {0, 1, 2, 3, ..., 8}, B = {3, 5, 7, 9, 11) and C = {0, 5, 10, 20), find
(i) A UbB
(ii) A U C (iii) BUC
(iv) AOB
(v) Anc (vi) B n C.
Also find the cardinal number of the sets B U C, A n B, An C and B​

Answer 2

from the question it is given that

(0,1,2,3,4,5,6,7,8)

B = (3,5,7,9,11)

C = (0,5,10,20)

A - C

A - C = (0,5)

Cardinal number of set A - C I.e = 2
