發問:
1. 四人分先後在一套啤牌抽取一隻牌, 抽出啤牌後不會放回, 請問, 抽出葵扇 A 的機會, 是否每人均等?? 2. 如抽出啤牌放回, 則每人抽出葵扇 A 的機會又如何? 可以的話, 能否提供數據證明!!
最佳解答:
Suppose the four people are A,B,C,D A selects first. ___________________________ 1: P(selection of A)=(1/52) P(selection of B in second time)=(51/52)(1/51)=1/52 P(selection of C)=(51/52)(50/51)(1/50)=1/52 P(selection of D)=(51/52)(50/51)(49/50)(1/49)=1/52 Their probability for selecting spade A are same ________________________________________ 2: P(A)=P(B)=P(C)=P(D)=1/52 Their probability for selecting spade A is same.
