[問題] 請問統計問題
這是在問什麼，還有該如何解呢?
Let D1,D2,D3 be three four-sideddice whose sides have been labeled as follows:
D1:0333 D2:2225 D3:1146
These side are rolled at random. Let A,B,and C be the events that the outcome
on die D1 is larger than the outcome on D2, the outcome on D2 is larger than
the outcome on D3, and the outcome on D3 is large than the outcome on D1,
respectively. Show that (a) P(A) =9/16, (b) P(B) = 9/16, (c) P(C) =10/16.
Do you find it interesting that each of the probabilities that D1 "beats"
D2,D2 "beats" D3, and that D3 "beats" D1 is greater than 1/2 ?
Thus it is difficult to determine the "best" die.
謝謝~
