例如，如果X等於背包中的書籍數量，則X是離散的隨機變量。 如果X是書的權重，則X是連續的隨機變量，因為權重是經過測量的。 如何定義隨機變量非常重要。

結果 (英文) 1:

For example, if X is the number of books in the backpack, then X is a discrete random variable. If the weight X is a power of, the continuous random variable X is, because the weight is the result of measurement. How to define a random variable is very important.

For example, if X is equal to the number of books in a backpack, X is a discrete random variable. If X is the weight of the book, X is a continuous random variable because the weight is measured. How to define random variables is important.
