Conditional Probability 8. Image source. Conversely, if all we know about X is a collection of X-scores, then the average, median and mode of those scores are our best estimates of the expected value, median and mode of X. Please support IntMath! Discrete random variables that can take on only finitely many values like the outcome of a roll of a die are called finite random variables. If we perform a sequence of n independent Bernoulli trials, then some of them result in success and the rest of them in failure. Try before you commit.
