Let the S = {0,1,2,3,4,5,6,7,8,9,10} be the sample space of a
random experiment. Suppose A is the event that we observe a number
less than 3 and B be the event that we observe a number greater
than 8. Determine the event that either A occurs or B occurs.

Proposition 16.4 Let S be a non–empty finite set.
(a) There is a unique n 2 N1 such that there is a 1–1
correspondence from {1, 2,...,n} to S.
We write |S| = n. Also, we write |;| = 0.
(b) If B is a set and f : B ! S is a 1–1 correspondence, then B is
finite and |B| = |S|.
(c) If T is a proper subset of S, then T is finite and |T| <...
