The examination for this material consists of 3 hours of multiple-choice questions and is identical to CAS Exam 1.

The purpose of this course of reading is to develop knowledge of the fundamental probability tools for quantitatively assessing risk. The application of these tools to problems encountered in actuarial science is emphasized. A thorough command of probability topics and the supporting calculus is assumed. Additionally, a very basic knowledge of insurance and risk management is assumed. A table of values for the normal distribution will be included with the examination booklet.


Candidates should be able to use and apply the following concepts in a risk management context:

Study Notes

Discrete Distributions


    • In the formula for Variance of Uniform you have a mistake, the term you are subtracting should be <math>\left( \frac{\sum_{i=1}^{n} x_i}{n} \right) ^2 </math> I believe. Also, at least for me, where it says <math> n \in ...</math> it's coming out weird, is that supposed to be <math> n \in Z^+</math> ?
    • In general (continuous case) the variance of U[a,b] is <math>\frac{\left( b - a \right) ^2}{12}</math>. This follows immediately from the fact that the variance of U[0,1]=1/12 and a U[a,b] is a shifted and rescaled U[0,1]. The discrete case has a correction factor and so it isn't just n^2/12. the variance for discrete is is <math>\frac{n^2 - 1}{12}</math>
