# MA375: Lecture Notes

Fall 2008, Prof. Walther

## Two problems and independence

Today in the end of the lecture Dr. Walther discussed two probability puzzles:

1) one of the numerous interpretations of the Monty Hall problem

2) what is the probability that the random secant is greater than radius in a circle?

I think that these probability puzzles are very interesting. The first one seems so simple, yet without having someone explain it to me, I would never realize that switching makes a difference even though I knew that the answer was probably not simply 1/2 if he took the time to tell it in class.
