Hi all,
Edit: Here's the question, in case you guys don't have the book:
In the Drude moel the probability of the electron suffering a collision in any infinintesimal interval dt is just dt/T.
a) show that an electron picked at random at a given moment had no collision during the preceding t seconds with the probability exp[-t/T]. Show that it will have no collision during the next t seconds with the same probability.
I'm trying to figure out how to get the exp[-t/T] part, 'cause nowhere in the chapter does it show a probability as XX exp[-t/T].
Please just help me get started. Any reference equations would be good...
Thanks!
