Chapter 2 Statistic ReviewA.Random variables;1.expected value:Define ：X is a discrete random variable，“ the mean （or expected value）of X " is the weighted average of the possible outcomes，where the probabilities of theoutcome serve as the appropriate weight。
p i is ith of prob。
, i=1，2，……nInterpretation: The random variable is a variable that have a probability associated with each outcome. Outcome is not controlled.Discrete random Var. ：has finite outcome，or outcome is countable infinite。
Continuous random Var。
: uncountable infinite outcome, the probability of each outcome is small because of too many numbers.For normal random Var.，probability density function is used to calculate the probability between the are。
E（)：the expectations operator,→… “ sample mean”, used to estimateThe is changed from sample to sample。
