### Counting and Probability IA 8.23 B

Re: Counting and Probability IA 8.23 B

For this question the pin can land in *any* angle. This is similar to those problems where we pick a real number, say, between $0$ and $1$. Since there are an infinite number of points possible, we use the length of the desired set instead. Answering this question might help: What is the length of a point? What is the combined length of two points?
