Question 424646: on a 3 question, True or False test, how many tests could you complete to be certain all possibilities are covered and one test will be 100% perfect.....and is there a mathematical equation to arrive at this answer so that you could solve for an 6, 7, 8, 9, or 10 question test

You can put this solution on YOUR website! on a 3 question, True or False test,
