Had to make a tough choice regarding my MacMini (format and reinstall OS, or find another way) before my sister visits with my backup data on her external hard drive (thought it would be tomorrow, but instead is next week). Resorted to using a pretty interesting Excel document/program I made some time ago, based on the rules of coin-tossing taken to another level. (Turns out, the choice to format and reinstall won, "best of 3 'best of 21s'" (3 rounds of best of 21)).
Simple description:
Toss all kinds of coins (penny, nickle, dime, quarter), be it what's currently in your pocket or a control amount (5 of each or something). Count how many of each kind are heads and tails, and mark that down; place a value on them based on their value (1-point per penny, 5-per nickle, 10-dime, 25-quarter), and mark down for each side facing up (total tails coins and heads coins; greater amount wins), tally the total value of the sides facing up (quarters are a major help, but pennies can surprise you), and to place one last parameter to ensure only one side wins, you then add the sum amounts and values.
For best results, hold down F9 (recalculate) for a few moments while looking away from the screen, let go and look at the upper-left corner to see the winner; details are also visible. For even better results, play best of 21. In that long cell, fill in A or B, depending on which side wins (color coded for convenience).
I took a screenshot of my excel document to show how it works:
Best Bets was an attempt to make an odds payout kind of setup if you want to make this a gambling game. SUB VAL was to ensure that the determination of which sides win is calculated properly regardless of variables (based on variable - variable = variable difference used on TOTAL); it works in concert with the conditional formatting tool.
Checksums were made to ensure the counters worked properly (COUNT and COUNTIF functions), counting the total flipped, which sides won, and the total of sides won = total flipped. Keep the math consistent if you don't go the full 21.
I like finding old things like this I make on a whim. Every cell in light-blue can be edited. Decision name (In this case, ACCEPT and REJECT, can also be HEADS and TAILS), you can toss as many coins at whatever value you want. The more important the choice, the more coins or value is tossed in. Default is USD currency values, about 25 of each coin. POT MAX is the sum of the coins, and below that cell is the total sum of all the coin values (25 of each coin = 1025 (or $10.25)); POT VAL, like stated before, is the sum of the total value and the total amount of coins (in this case, 1025 + 100 coins = 1125 (or $11.25)). Reference aside, it also assists in doing the math to calculate the other side (simply TOT - A = B).
If you want, I can upload it for anyone to use. Great for making choices between 2 things.
And in other news, a pretty neat thunderstorm is headed my way. Gonna watch it for a bit.
