Answer» Answer: The EXPECTED value of random VARIABLE X is often WRITTEN as E(X) or µ or µX. The expected value is the 'long-run mean' in the sense that, if as more and more values of the random variable were collected (by sampling or by REPEATED TRIALS of a probability activity), the sample mean becomes closer to the expected value. |
