Baye's rule 剛開始問了這個問題
suppose P(B|Ak) and P(Ak) ? what is P(Ak|B)?
Example
Suppose there are three chests each having two drawers. The first chest has a
gold coin in each drawer.the second chest has a gold coin in one drawer and a
silver coin in the other drawer. and the third chest has a silver coin in each
drawer. A chest is chosen at random and a drawer opened. If the drawer contains
a gold coin?
答案不是1/2
Baye's rule 可以幫你去解決這類的問題
他的前提有點多 可能會沒辦法知道前面的那些機率值
