英语翻译Quickly picking up the diary,Phil (flipped) straight to 英语翻译 Quickly picking up the diary,Phil (flipped) straight to the last entry and began reading it. 这里的 flip straight 是啥意思呢? 快速的捡起了日记本,Phil xxxx 走向了入场处然后开始朗读? 本来我填了 frantic .想大概意思是手忙脚乱的笔直走向了入口处（straight不就是笔直的意思吗） 为啥是如果是想翻译成快速浏览了一下然后走向入口处.也不能flip直接接在 straight 之前把-.奇怪. 小白宝贝2121年前4: 我心已完共回答了12个问题 | 采纳率100%

这里意思是捡起日记,直接翻到最后一"篇",开始读下去.
flip 翻
straight 直接
这里关键entry不是入口,是指书页条目,项目

又是概率问题~A two-sided coin is flipped four times. Given that th 又是概率问题~ A two-sided coin is flipped four times. Given that the coin landed heads up more than twice, what is the probability that it landed heads up all four times? 我用的是TI-84 Plus的计算器 最好能用nPr和nCr的符号讲解 万分感谢~ eetocs1年前1: wf888820506 共回答了24个问题 | 采纳率95.8%

已知向上超过2次,3次的有C（3,4）＝4种,4次的有C（4,4）＝1种
所以共有1+4＝5种情况,4次向上只有一种情况,几率为1/5

sat2 A two-sided coin is flipped four times.Given that the c sat2 A two-sided coin is flipped four times.Given that the coin landed heads up more than twice,what is the probability that it landed heads up all four times? 答案是1/5 why BRIGHTGONG1年前1: wongr123 共回答了17个问题 | 采纳率94.1%

Well, since it has been flipped four times, and more than twice with heads up (which is, at least 3 times), only the last time counts.
It is very obvious that the last time will see this two-sided coin either landed heads up or tails up, and the probability is 50%.
So the answer is 50%.

A weighted coin is flipped three times with P(H)=1/3.What is A weighted coin is flipped three times with P(H)=1/3.What is the probability that heads come out exactly twice given heads come out at least once? 东方路灵1年前2: gabyee 共回答了26个问题 | 采纳率92.3%

得到0个head的几率是 1*1/3的零次方*2/3的三次方=8/27
得到2个的几率是 3*1/3的二次方*2/3的一次方=2/9=6/27
6/(27-8)=2/7
不懂的话可以追问

一个求概率的数学题：If a certain coin is flipped,the possibility that 一个求概率的数学题：If a certain coin is flipped,the possibility that the coin will land heads is 1/2.If the coin is flipped 5times,what is the possibility that it will land heads up on the first 3 flips and not on the last 2 flips? mickeycxy1年前2: 斯诗共回答了13个问题 | 采纳率84.6%

分步原理意思是前三次有图案后两次不出现图
3次不出图0.5^3=1/8 出图1-1/8=7/8
后2次不出1/4
∴概率P=7/8*1/4=7/32
还是说题目意思就是前3次图后两次字那么每轮概率都是1/2
1/2^5=1/32
