: by正在努力搜尋二手書中的人....
p34.
8.Let A1, A2......An be n events. Show that if
P(A1)=P(A2)=......=P(An)=1
then P(A1A2A3...An)=1.
9.(a)Prove that ∩[n=1~∞](1/2-1/2n,1/2+1/2n)={1/2}.
(b)Using part(a), show that the probability of selecting 1/2 in a random se-
lection of a point from (0,1) is 0.
10.A point is selected at random from the interval(0,1). What is the probabil-
ity that it is rational? What is the probability that it is irrational?
就不翻譯囉？剩下兩小題書上沒有，反正老師有說明過了。
