		<description><![CDATA[Linear programming is often a favorite topic for both professors and students. The ability to introduce LP using a graphical approach, the relative ease of the solution method, the widespread availability of LP software packages, and the wide range of applications make LP accessible even to students with relatively weak mathematical backgrounds. Additionally, LP provides [...]]]></description>

		<description><![CDATA[In a group of at least 23 randomly chosen people, there is more than 50%  probability that some pair of them will have the same birthday. Such a result is  counter-intuitive to many. In probability theory,  thi is known as the birthday problem, or birthday paradox. Here is how we  calculate [...]]]></description>

		<description><![CDATA[1  When can you use the binomial formula?

We want to know how many times something does or doesn’t happen e.g. rolling a
die multiple times:

can use binomial if we want to know “number of sixes”
can’t use binomial if we want to know “sum of rolls”



2  Where did that binomial coefficient come from?

Say you have [...]]]></description>
