推荐答案

更一般的说，这通常是相反的.

概率和统计定律通常可以在纸上找到.
但是实际上，统计数据的计算和使用通常不需要计算机.

More generally this is often the other way round.

Probability and statistics laws have generally been found on paper.
In practice though, the calculation and use of stats will more often than not require computers.

"The advent of the computer has certainly revolutionised the practice of
statistics." (Speed, 1985).

统计和计算机

在任何情况下，概率和统计信息都会在整个软件中使用，有时甚至会在您不希望使用的地方使用.
其中之一就是SQL查询优化器.

Statistics and the Computer

In any case probability and statistics are used all over the place in software and sometime in places you would not expect.
One of them would be the SQL query optimizer.
