Compilation of Probability Problems

[securitygeek]

Folks,
I have put together some 50 + probability and permutation/combination problems. I don't think problems harder than these will show up on the actual exam. In short, I have a feeling that if you look at these, you should be able to solve the probability problems that appear on the exam.

Good luck!

thanks man, we all appreciate your effort in putting those together!

Cheers mate!

thanks!

I was looking for something to help me strengthen out my combination/probability skills.


note: Found a couple of mistakes in the first few (qt6. credit card had 6 digits btw) and some qts can be clearer (qt 4).

I know Erin rarely stickies things when people tell him to, but I really think that this should become a sticky, considering that everyone stresses out over probability so much. This will provide them with more than ample practice!

Ok..I guess I should have also added a disclaimer. ** PLEASE USE AT YOUR OWN RISK**. I am not the person who wrote these problems. I have only collected them from various posts in this forum. There may be mistakes and ambiguities which can be discussed on this forum. But overall, I think this is a pretty well rounded set of questions.

I hope these will help.

Jemily,

Your set of docs are very helpful as well. I hope Erin can make this post a sticky so everyone will have these for their reference. Or else, they get lost in the jungle of posts.

Thanks!
