flat tire at any point on my ride. Let X denote the distance away from my office on my ride to work.

a) Draw the probability density function, f(x), for me getting a flat tire on my way to work at a distance x away from my office. Be sure to label the height of f(x).

b) What's the probability that a given flat tire happens within a half mile of my house?

c) What's the probability that a given flat tire happens within a half mile of my office?
