To Graph a Binomial Distribution

  1. Input the possible number of successes (from zero to n) in L1.
  2. Scroll right and up, using the arrow keys, until the L2 is highlighted.
  3. Press 2nd VARS and select binompdf from the DISTR menu.
  4. Input the value for n, a comma, the value for p formatted as a decimal, a comma, L1, and a closing parenthesis. The command should look like L2=binompdf(n,p,L1).
  5. Press ENTER, and the calculator will store the probabilities attached to each number of successes in L2.
  6. Press 2nd Y= to go to the STAT PLOT menu.
  7. Press ENTER to select plot 1.
  8. Press ENTER when the word ON is highlighted to turn the plot on.
  9. Use the arrow keys to scroll over until the histogram graphic is highlighted, and press ENTER.
  10. Set the Xlist to L1.
  11. Set the Freq to L2.
  12. Press WINDOW.
  13. Set up the window as follows:
  14. Xmin: -0.5
  15. Xmax: n+0.5
  16. Xscl: 1
  17. Ymin: 0
  18. Ymax: a little higher than the maximum probability from L2
  19. Yscl: Could use a lot of things here, but 0.05 works pretty well
  20. Xres: 1
  21. Press GRAPH. The calculator should now display the graph of the specified binomial distribution.
