What is the probability that after you flip 7 coins, all of them will be tails? The answer is 1/2^7, which is 0.7% that all coins will show tails. When it comes to true/false questions, the probability is the same. There is a 0.7% chance that a student guessing totally at random will get all seven true/false questions wrong. The percentage should be even lower given that the student actually studied. Well, people, this just goes to show that you can't trust statistics. I got all seven true/false questions on the test wrong. Because I did fairly well on all the other questions, only losing 1.5% on short answer and 6% on the multiple choice questions, I pulled through with a B. I really need to learn how to tell misleading statements that sound true from factual statements that sound false.
P.S. DNA is negatively charged. Who knew!

ReplyDeleteAs frustrating as it must be for you, it really is kind of funny that you got every single T/F question wrong. I mean, that's really hard to do...
