NOTE: random Variables Can Have the Same Distribution without Being the Same Random Variable. Consider two consecutive daily number draws as in Example 3.1.7. The sample space consists of all 6-tuples , where the first three coordinates are the number drawn on the first day and the last three are the numbers drawn on the second day ( all in the order drawn). If s = , let and let . It is easy to see that and are different functions of s and are not the same random variable. Indeed, there is only a small probability that they will take the same value. But they have the same distribution because they assume the same values with the same probabilities. If a businessman has 1000 customers numbered 0,…,999, and he selects one at random and records the number Y , the distribution of Y will be the same as the distribution of and of , but Y is not like or in any other way.
