We'll talk more about the number of ways to rearrange a word when some of the letters are duplicates on Thursday.

Examples 5n and 5o are somewhat more complicated than the rest of the examples in Section 2.5.

Your first midterm will take place on February 18. You can use the midterm I gave last spring as a practice midterm. I expect you to be able to do all the problems on this midterm by the time you take yours (though we haven't discussed how to do the last one yet, we will next Tuesday).

A general knows that an attack is coming, and he knows that the enemy will attack on the left, the right, or the center. One of his lieutenants tells him that the probability of an attack on the left is 1/5, the probability of an attack on the right is 3/10, and the probability of an attack on the center is 1/2. His communications officer has been hearing radio traffic, and he knows from experience that the probability of hearing this chatter given that the enemy will attack on the left is 1/5, the probability given that the enemy will attack on the center is 7/10, and the probability given that the enemy will attack on the right is 1/10. Given that this chatter is, in fact, being heard, what are the probabilities of an attack on the left, the right, and the center?

Keep in mind that while Poisson and binomial random variables both count the number of events/successes, the events for binomial random variables are triggered by something particular (flipping a coin, rolling a die, etc.) while the events for Poisson random variables happen at random (earthquakes, typos, etc.).

Last year's second midterm can be found here. I think you can do all the problems on it!

The main thing you should remember about the formulas for continuous random variables is that if you would use a sum in the discrete case, you need to integrate in the continuous case, and the pdf plays the same role in the computations that the pmf did in the discrete case.

All but the first example in Section 6.7 are more complicated than we'll go through in this class.

We're skipping Section 7.3 even though it's on the schedule. It's by far the least important for our purposes.

Most of the examples in Section 7.4 are quite reasonable.

Here's the final exam I gave last spring.

Good luck studying! I'll have your last homeworks graded by the start of office hours on Monday.
