excel中 =CHOOSE(MOD(ROW(B4),3)+1,&&,B$1,OFFSET(B$1,ROW(B5)/3,)) 这个公式怎么解释
提问者采纳
这个公式返回B$1单元格的值---------------解释-----------ROW(B4) :
返回 B4单元格的行号
(4)MOD(ROW(B4),3)
返回 B4单元格的行号除以3得到的余数
(1) MOD(ROW(B4),3)+1 :
为待选参数序号
(第2个)&&,B$1,OFFSET(B$1,ROW(B5)/3,)
依次为3个待选参数 OFFSET(B$1,ROW(B5)/3,)
B$1下第ROW(B5)/3个单元格的值

出门在外也不愁贝叶斯定理公式：有可能 P(A|B)&1 如何解释_百度知道
贝叶斯定理公式：有可能 P(A|B)&1 如何解释
贝叶斯定理公式：P(A|B)=P(B|A)*P(A)/P(B) 如果P(A)&P(B)
且P(B|A)&P(B)/P(A)的话
则P(A|B)&1
如何解释呢是否意味着由相对小概率的事件推断相对大概率事件的发生概率时，大概率事件有可能是必然发生的。
提问者采纳
P(B|A)=P(AB)/P(A)&P(B)/P(A)是不可能的, 因为P(AB)&=P(B)
继续请教贝叶斯定理公式：P(A|B)=P(B|A)*P(A)/P(B) 里面的 P(B|A)
P(B) 这三个量是不是独立统计得到的，如 P(B|A) 的话就是 在A发生m次有n次B也相伴发生了 则近似为n/m 。
是这个意思

不可能P(A|B)*P(B)=P(B|A)*P(A)=P(AB)而P(AB)&=P(A)P(AB)&=P(B)因此P(A|B)&=1
Like the previous design of the adidas The Kobe inspiration from the Audi TT sports car, like,
Air Jordan 14 's design inspiration comes from the same car - Jordan's car Ferrari 550 Maranello, a few design elements unique shoes and vehicles will be linked.
Including the Ferrari logo trademark trapeze-shaped, perforated uppers of the entire striate cortex (except for individual color section), followed by a similar design of tread patterns, but also in the middle of palm vent dissection. However, removal of visual intuitive feelings, real shoes and cars will be linking their shared by the soul of non-binding and does not yield the expression.
Air Jordan retro 14
triangle on both sides of the front design is very easy to fold effect,Nike Air Jordan 6, dressed in a long time even after the cracks, but it is praiseworthy is that the color of the surface coating of the durability, my pair of Air Jordan XIV red / white shall, from the 99 years that has yet to fade phenomena occur (however, because the pigment composition of the problem, Nike Inc. has all the toxic elements in the recovery of the child standard shall sneakers Air Jordan XIV). Also can be seen outside of the Air Jordan XIV at the end of the use of the traditional design of word patterns, even if playing on a concrete floor, but also showed good durability, but this design also provides excellent performance friction grip.
First of all,
Air Jordan 14 shoes
is a very comfortable pair of shoes. In fact it is the interior design of the simplified, in-house with a relatively thick pad of memory foam for the ankle to provide a very good comfort. In addition, his use of asymmetrical design of the site - inside slightly higher than the lateral. Higher than the medial part of the ankle live coverage, effective to prevent a sprained ankle. The lateral part because taking into account the protection of the ankle will not achieve a very important role, it has slightly lower, saving materials and reducing the weight of the shoes.
Order to become a pair of Air Jordan XIV shoes are very comfortable, another important factor is the one at the end of the design. Large areas of hard board in charge of support for the stability of the shoes help a great deal. Unique air flow inside the device makes XIV became the Air Jordan series,Authentic Jordan Shoes, the best performance of a ventilation.
Apart from the above mentioned number of
Jordan 14 shoes
sudden special design elements, it also provides excellent shock absorption performance of the buffer. XIV of the shock absorber system uses a Zoom Air shock absorption unit, but it is different from the damping unit is now in charge of some of the whole of the Zoom Air, instead of using the pre-and post-charge separation in charge of the Zoom Air shock absorption unit. The benefits of doing so is able to pre-charge after the charge or under different circumstances to make their own rapid reaction. Similarly, after the separation of its arising as a result of the buffer effect of weakening,Nike Air Jordan Shoes, so the relatively large number of body play center location is not very suitable for. But some speed,Air Jordan Shoes 2, hit the back into the basket or stop in more easily in.
Air Jordan XIV is a unique family of
Air Jordan 1 's. It has its own unique style, did not mimic the design style of their predecessors, have not been emulated by younger players.
Overall, Air jordan 14 is the closest I've seen so far in the perfect pair of shoes. Excellent comfort and excellent shock absorption properties of the buffer, the shoes are lightweight and good ankle protection,Cheap Air Jordan Shoes, all of this created a great Air Jordan XIV. If the capacity of performance analysis point of view, then, Air Jordan XIV sports car like Ferrari 550 Maranello and the Jordan I, is near perfect......

是的话返回1，否返回空文本；否则进一步判断C蹲莘厕匪丿睹恩谜5是否大于0，该函数所在单元格为空如果B5和C5至少有一个为空的话
图片不清楚，说明也不清楚，大盖意思是：序号列，假如该记录所在行日期没有输入数字或输入0，则序号为0，否则为上一行序号加1. 我们知道，对于整数a
