We say that X and Y have the same distribution if Splet25. nov. 2015 · The standard convention, which works nicely, is to use upper case for a random variable and lower case for a plain old number. So when we write we mean the probability that the random variable is less than or equal to the number . So don't write things like as you did above, because you'll just confuse yourself. cheap hotels in the backs https://bukrent.com
