What is the probability that event E or event F or both will occur?
(1) The probability that event E will occur is 0.6.
(2) The probability that event F will occur is 0.4.
答案為什麼是E呢? 想不通說~~

pamelatsai \$m[1]:題目關鍵應該在the greatest possible value --->neither of these two events will occur
這種情況發生在A 和B兩者發生機率完全重疊的時候~
當發生B時機率0.68已經完全吸收發生A的機率0.54
所以兩者都不發生的最大可能機率就是1-0.68=0.32
寫得不好~希望你能看的懂
