Difficult questions asked by someone texting me .

There are some things upstairs that I haven't considered.

Probability problem: There are two situations in the landlord's problem: (1): put it back after picking the easter egg every time (2): don't put it back after picking the easter egg every time.

The first type: every time it is 3 15 = 1 5, three times is 3 5, theoretically pick 5 times will be able to win.

The second type: the first win: 3 15, the second win, that is, the first time did not win: 3 14, the third time, the first two misses: 3 13, the overall probability of winning is: 3 15 + 3 14 + 3 13 completed.

Upstairs didn't answer quite right.

If you put the egg in it after pumping, then it is.

Drawn once, secondly, thirdly.

If you don't put the egg in it after pumping. Then there it is:

Drawn once, secondly, thirdly.

The result is not counted, you count it yourself!

The first time is 1 5 chances out of 15 out of 3, the second time there are 2 out of 14 with 1 7 chances, and the third time 13 out of 1 1 13 is added up, this kind of non-repeating does not put back sampling. If you don't draw and put it back, then it's 1 5 1 5 1 5 3 5

All combinations: choose any 3 out of 15, there is c15 (3) = 15 * 14 * 13 3!

Non-winning combination: choose any 3 out of 13, there is c13 (3) = 13 * 12 * 11 3!

Probability of not winning: Divide the two: 11*12*13 (13*14*15)Probability of winning: 1 minus the probability of not winning = 13 35

This is a permutation problem: there are 15 eggs in total, and you can choose 3 of them: c53, and then the prize is c3 1 times c12 2 plus c3 2 times c12 1 plus c3 3

Enough of your hints, as long as there is affection, even if you have a little good impression of you, you will try to think in which direction, don't be afraid, and don't regret is the experience summed up by the sages, take your time, ask her out to play to see his reaction, if he is happy, say that there are only two of us, and if he is unhappy, say find a few more people.

It's so obvious, buddy, people are definitely interesting to you. However, you really didn't reply well to this text message, and missed a chance to break fast. is also too anxious, love should be slow, ready to fight a protracted battle.

It has a lot of meaning, and it will definitely be chased.

Dizzy, what are you? The hint is not obvious enough.

Wouldn't you just send a word document to your phone with a flying message from your computer, and you wouldn't be able to send a message to your phone, would you?

If your mobile phone is advanced, you can read the text document, which is the legendary txt, you can also copy it with this, copy it and send it out, don't you?

The first two are right, either send it to your mobile phone through Feixin on the computer, or buy a smartphone to write a word document.

That depends on whether the mobile phone supports it.。。。

The failure to send text messages on the iPhone may be caused by a problem with the SMS center.

Solution: Method 1:

1. Shut down the computer and re-insert the SIM card;

2. Then open the dial button lead dial interface of iPhone, take the mobile number as an example, enter *5005*7672*+8613800755500, and click the dial button;

3. According to its instructions, set an SMS center number.

Method 2: 1. Follow the path of [Settings]-[**]-[Local Number] to delete the original number with 86 in the mobile phone, and then re-enter your mobile phone number.

What's the situation? Do you have**.

Absolutely! As long as someone is interested in helping you!

Of course it's true.,,I'm not going to be you now.。。

Really, tried....After all, it cost money....(1 gross).

Text messages are also sent only after passing through the computer.

So all you have to do is join the dedicated information service area.

What coaches? The football coach sends the football mobile phone pendant and so on.
