Sample space associated with throwing a die s = {1, 2, 3, 4, 5, 6}
A: An even number turns up = {2, 4,6}
B: A prime number turns up
= {2, 3, 5}
1)Event A or B ≡A∪B
= {2, 3, 4, 5, 6}
2)Event A and B ≡A∩B
= {2}
3)Event A but not B≡A−B
= set of elements in A which are not in B
= {4, 6}
4)Complementary event of B = B`
= {1, 4, 6}
