Announcements: Please remember that HW5 is due tonight. Solutions will be posted shortly, as well as the next homework assignment HW6.


• Video 1: Types of Random Variables, and a first example: Bernoulli random variables: Download file or watch below


• Video 2: Binomial random variables: Download file or watch below


• Video 3: Problem involving a Binomial random variable: Download file or watch below


• Video 4: Comparing shapes of Binomial distributions: Download file or watch below

You can play with the parameters of a Binomial distribution and see how they affect its shape here.


• Histograms with $n=5,50,100$ and $p=\frac12,\frac14,\frac{1}{10}$. Click on the image to make it larger, and use the linkĀ above for an interactive way of visualizing this.

$p=\frac12$

$p=\frac14$

$p=\frac{1}{10}$





• Video 5: Problem involving conditional probability and a Binomial random variable: Download file or watch below

Some more details on this problem and a concrete numeric realization are given in today's notes.
