Ubuntu18 安装telnet 报错Excess arguments.

在Ubuntu 18上安装telnet命令时，可能会遇到Excess arguments错误。这是因为Ubuntu 18默认没有安装telnet，需要先安装telnet软件包，然后再使用telnet命令。

要安装telnet软件包，请在终端中运行以下命令：

sudo apt-get update
sudo apt-get install telnet

安装完成后，您可以使用以下命令来测试telnet是否正常工作：

telnet hostname port

其中，`hostname`是您要连接的主机名或IP地址，`port`是您要连接的端口号。如果telnet连接成功，则会显示连接成功的消息。

Excess probability

Excess probability is the probability of an event occurring that is above the expected or baseline probability. It is the difference between the actual probability and the expected probability of an event occurring. For example, if the expected probability of a coin landing on heads is 50%, and the actual probability is 60%, then the excess probability is 10%. Excess probability is often used in statistical analysis to determine whether an event is statistically significant or not. A high excess probability indicates that the event is unlikely to have occurred by chance alone, and may be due to some other factor or variable.

Excess-6 code to Excess-3 code

To convert Excess-6 code to Excess-3 code, you can follow these steps:

1. Subtract 3 from each decimal digit in the Excess-6 code.

2. Convert the resulting decimal digits to their corresponding Excess-3 code.

For example, let's convert the Excess-6 code "10110011" to Excess-3 code:

1. Subtract 3 from each decimal digit in the Excess-6 code:
- Decimal "13" becomes "10"
- Decimal "9" becomes "6"
- Decimal "11" becomes "8"
- Decimal "11" becomes "8"

2. Convert the resulting decimal digits to their corresponding Excess-3 code:
- "10" becomes "0010"
- "6" becomes "0101"
- "8" becomes "0110"
- "8" becomes "0110"

Therefore, the Excess-6 code "10110011" is equivalent to the Excess-3 code "001001100110".
