Big brother, big sister, uncle, aunt are all coming in 5

I want to learn how to use a computer! Start with the basics!

Start with the hardware and understand the principle!

Then understand DOS again and master more tricks!

How old are you? There are too many people eating the computer industry now.

If you're young, consider changing careers

Three days and four nights! That's what you're done. Whatever you do well in these years has a future, depending on whether you are better than others.

Let's be honest. Now that you know about hardware, you're in this business. It doesn't matter which line. As long as you learn well, it will be very profitable. Because no matter which industry is strong, it can survive.

You go and take a CCIE

Keep you a high salary.

It's best not to get involved in the IT industry.

I'm uncle, you told me to come in, but I won't.

New Year's greetings! Call me to learn from me, look at tutorials, examples, graphic design on the Internet, and you're done! I am a stark example!

If you learn both, you don't have to worry!

Go buy a computer, you can do it as big as you want! Assemble the machine, disassemble and disassemble the machine, just have the strength! Brains can be used less!

Guan Yu ran away without taking the umbrella, then met Cao Cao and Sun Quan, and then died. Zhang Fei was so angry that he took two umbrellas and rushed out, and then he was crushed to death by the umbrellas. Liu Bei saw an umbrella, and just wanted to take it, but was robbed by Zhuge Liang, so he cried and cried, cried, and cried to death.

Seriously, it should be one-sixth.

There is something wrong with this question, only two people get it right, it means that the third person can't get it right, and if two people get it right, the third person will definitely get it right, so this is either one in six or 0

The probability of getting the first umbrella right is 1 3

The probability of getting the second umbrella right is (1-1 3)*

The probability of getting the third umbrella right is (1-1 3).

I don't have a calculator at hand, so I'm sorry that the calculator on the computer can't be opened.

After a little calculation, the results will come out.

If only two people get it right, doesn't it mean that all three of them got it right? Isn't it 1 9

What the? Don't want to explain, it's bad for IQ.

Dial 110 directly out of the brain teaser

Is this an emotional problem?

Speechless. Effervescence.

1. ABC is greater than 0, and C is less than 0, so AB is less than 0, so BC

2. Set the original price x yuan, then 85%x=y, x=y 85%=100y 85

Total balls: 10 + 5 + 15 = 30.

Probability of touching a white ball: 10 in 30 = 1 in 3

Probability of touching a black ball: 5 out of 30 = 1 in 6

Probability of touching a red ball: 15 out of 30 = 1 in 2

I have a new question and ask for help, thank you!

The probability of a white ball is: 10 (10 + 5 + 15) = 1 3

The probability of a black ball is: 5 10 + 5 + 15 ) = 1 6

The probability of a red ball is: 15 10 + 5 + 15) = 1 2

A total of 30 balls, any three combinations, for a total of 30 29 28 24360 (the first 30 are optional, there are 29 left, so the second 29 optional, the third 28 optional).

The combination of all three colors is 10, 5, 15, 750

So the odds of touching three balls 750 24360 are no more than 4

Assuming that the original plan is to travel x kilometers per day or hour, S = 10x8 (x + 15) yards in -10x=20

Launch x=50

Finally, the original = 10*50=500

Box volume: 40x30x25 = 30000 (cm) Water volume 15x30x40 = 18000 (cm) 6 small cubes: 10x10x10x6 = (6000cm) Water plus cube:

18000 + 6000 = 24000 (cm) Water height: 24000 40 30 = 20 (cm).
