A die is thrown. Describe the following events:
(i) A: anumber less than 7 (ii) B: a number greater than 7
(iii) C: a multiple of 3 (iv) D: a number less than 4
(v) E: an even number greater than 4 (vi) F: a number not less than 3
Also find `A uu B, A nn B, B uu C, E nn E, D nn E, A - C, D - E, E nn F',F'`

Answer

(i) `{1, 2, 3, 4, 5, 6}` (ii) `phi` (iii) `{3, 6}` (iv) `{1, 2, 3}` (v) `{6}` (vi) `{3, 4, 5, 6}, A uu B = {1, 2, 3, 4, 5, 6}, A nn B = phi, B uu C = {3, 6}, E nn F = {6}, D nn E = phi`.
