Here are AP Statistics notes on A RANDOM VARIABLE’S EXPECTED VALUE & STANDARD DEVIATION! Create probability models of discrete random variables, use a normal model to calculate the probability of a continuous random variable, and calculate the expected value and standard deviation. Great for AP Statistics Exam review prep!

Aligns with AP College Board's objectives and standards for AP Statistics Unit 4: Probabilities, Random Variables, & Probability Models.
