## Replies to: ap stats easy or hard?

121Junior MemberThe community college I have taken some dual enrollment classes in has a stats class that's supposedly the equivalent of AP stats, and it's just one semester. The other classes I've taken that they claim are the same as APs actually are, so I don't believe it's easier than AP stats.

Since Heads and Tails both have 50%, an 80% increase would give Heads the unfair advantage of 90%, leaving the odds of getting Tails only 10%. Then, to get Tails as your third flip, you would have to NOT get Tails in your first two flips. The complement is 90% (since Heads is the only non-Tails), then in order to get a non-Tails two times in a row, you would have to multiply them. 90%x90%=81%. Now, for the third flip, it HAS to be Tails. This means that you would multiply 81% by 10% to get 8.1%. There is an 8.1% of having Tails be your third flip.

Do you see how fun that is?! I made that up as I wrote it! (not the answer, of course; just the question) If you stop thinking about the difficulty and start getting engaged in the topics, then it should be much easier! There are those classes that require you to skim through the lessons for two seconds and move on (AP Bio, AP World His, etc...), and there are the classes that merely require an understanding of the course. (AP Stats, AP Calc, AP Physics, I'm trying to think of non-Math classes :P ) As long as you understand what you are doing, then the class and exam should be nothing more than a breeze.

Since it's not calculus-based, a lot of other topics are barely touched on.
