Probability of guessing questions on a testProbability question: #3 20121001 19:50:11
Re: Probability of guessing questions on a testHi; With n = 8 and p = 1 / 3 and trials = 19. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20121001 22:25:46
