The mean (or expected value) of a probability distribution can be calculated by first making the probability distribution. Then multiply the possible values of the Random Variable by their probabilities (X*P(X)) then add all the X*P(X) up. On the TI 83/84 calculator you can 1) Enter the values of the RV's into List 1 (Press STAT, 1 (for Edit), highlist L1 and press CLEAR if needed, then enter values into the list) 2) Enter the probabilities into L2 (press > and then enter the values in the list. highlight L2 and press CLEAR first if needed). 3) 2nd MODE (to quit the list) 4) STAT, > (for CALC), select 1-Var Stats, List: L1 (2nd 1), FreqList: L2 (2nd 2). Then calculate. x¯ is the expected value (mean) of the frequency distribution. A game is played. If you win you gain $4. If you lose you lose $10. The probability of winning is 0.747. What is the expected value (mean)?

Kim and Susan are playing a tennis match where the winner must win 2 sets in order to win the match. For each set the probability that Kim wins is 0.59. The probability of Kim winning the set is not affected by who has won any previous sets. (a) What is the probability that Kim wins the match? (b) What is the probability that Kim wins the match in exactly 2 sets (i.e. only 2 sets are played and Kim is the one who ends up winning)? (c) What is the probability that 3 sets are played?

A probability distribution allows you to organize all possible outcomes of a random variable along with their corresponding occurrence probabilities. The expected value E (x) of a discrete random variable is calculated by multiplying each value that it can assume by its probability of occurrence and then adding the products.The following table shows the probability distribution for the time (in minutes) it takes for a computer to recover after a failure. What is the most likely wait time to use the computer again? Tiempo means Time and Probabilidad means Probability
