    Hi there, math geeks. Physics geek here. I came across this problem in Griffith's Introduction to Quantum Mechanics, and just can't decide how to attack it.
    I've done the previous problems, but this one just threw me for a loop. Can anyone give me some advice? Thanks!

    Google for "Buffon's Needle"; you will find plenty.
