Will it rain tomorrow?

Will it rain tomorrow? To be or not to be, that is a question.

This reminds me of Schrodinger's cat. Did the cat die before unpacking? The answer is unknown.

But there is something in this world called probability. The probability of accurately predicting whether Schrodinger's cat is dead is very small.

There is a high probability of accurately predicting whether it will rain tomorrow. This is determined by the principle of weather forecast.

Although with the progress of science and technology, the weather forecast is more and more accurate, but it can not guarantee absolute accuracy. Every year, the country still loses billions of dollars due to weather forecast errors.

So whether it will rain tomorrow will not be known until tomorrow.
