High School Velocity (Where did I go wrong?)
Of course, 400m + 300m = 700m So, if you run 700m in 200s (total time), your average velocity is what?- Kittel Knight

Bayesian Inference: Prob of Dry Pavement Outside House
Let's consider the chance of rain and no rain: --- 20% chance of rain --- 20% chance of pavement wet (it doesn't matter if the sprinkler is on or off) --- 80% chance of no rain --- 80% * 40% chance of pavement wet due the sprinkler 80% * 60% chance of pavement dry (cause there is...- Kittel Knight

Learn C Programming: Tips for Engineering Student
The best book I know is the first one: "The C programing Language", by Kernighan & Ritchie (the fathers of the C language). No several equivalents examples, not twice the same thing. It is a concise book, and each line is valuable.- Kittel Knight

Graduate Proving (a^n -b^n) Does Not Divide (a^n + b ^n): Divisibility Question
That is easy. a=3,b=2,n=2 implies a^n+b^n=13 which is not divisible by a^n-b^n=5. So, if it is not valid for 3,2,and 2, then it is not valid for all integers.- Kittel Knight

Graduate Solve the "Hardest Logical Puzzle Ever
Hi Dave, I want to solve it by myself, and I won't take a look there. Of course, someone could ask me so why did I read all these posts. Well, maybe the first post was not ok, and Russell Berty could fix something in the latter posts. So, I read them all. But I was not expecting any...- Kittel Knight
