Final I: Study Guide

  1. Find a factorial, permutation, and combination. 3 parts.
  2. Use empirical probabilities to find the sample size.
  3. Given a sample space S with each event equally likely, find probabilities of certain events happening. 5 parts.
  4. Poker problems. 5 parts.
  5. List the requirements for a standard maximization and standard minimization problem. 2 parts.
  6. Solve a system of linear equations using Gauss-Jordan elimination. You may use the calculator, but you must copy each matrix if you do.
  7. Add two matrices.
  8. Multiply two matrices.
  9. Find the inverse of a matrix.
  10. Find the determinant of a matrix.
  11. Short answer - when can you multiply two matrices.
  12. Short answer - when can you add two matrices.
  13. List two of the three elementary row operations.
  14. List three of the four requirements of reduced row-echelon form.
  15. Short answer - when can the inverse of a matrix be found (2 requirements).
  16. Find the payment on a retirement account.
  17. Complete the payoff table for a game so each event is equally likely. Create a probability distribution and find the expected value of the game. Identify the game as fair or not. 4 parts.
  18. Read the answers to the dual (maximization) and primal (minimization) problem. Be cautious of cleared columns which don't have a 1 for the non-cleared element. 2 parts.
  19. Find a joint probability distribution. Find some probabilities based on the table. Identify the events A and B as mutually exclusive, all inclusive, and/or independent. 9 parts.
  20. Find out how much money will be in a retirement fund upon retirement.

This exam will be worked individually.
