p.246 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.

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.

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