Computing Expected Value and Standard Deviation of a Probability Distribution
PHStat | Probability Distributions | Covariance and Portfolio Management
Enter the the number of different possible values as the Number of Outcomes.
Fill in the probabilities in column B labeled as P; fill in the values of X in column C labeled as X and the values of Y in column D labeled as Y in the new Covariance spreadsheet.

4. Obtain Binomial Probabilites
PHStat | Probability Distributions | Binomial
Fill in the appropriate Sample Size (n), the appropriate Probability of Success (p), a value 0 in the Outcomes From: edit box and the appropriate sample size (n) in the To: edit box.
Check the Cumulative Probabilities box.

5. Obtain Poisson Probabilities
PHStat | Probabilities Distributions | Poisson
Fill in the Average /Expected No. of Successes.
Check the Cumulative Probabilities box.
