# Probability is killing me!!!

I have having trouble understanding reading #8 (One of the last ones I need to do), has anyone else had the same problem? How did you overcome?

pls be specific.

Joint Probability is giving me alot of trouble along with when to use the mulitiplication rule and total probability rule

if you asked specific questions where you were having trouble, and people solved it for you… that will give you a better understanding and help you learn by asking more follow on questions or you could email me at cpkrish@yahoo.com and I can try and help. CP

What specifically are you having trouble with? Probability has been one of my weak areas, but that should not hinder one in understanding the concepts. If I recall correctly, joint probability was referenced in calculating expected returns and covariance. Are you having trouble with the calculations? Multiplication rule ties in with joint probability. Provide some examples and you’ll get some help. If you want a true primer on probability, try brushing up on set mathematics–unions, intersections, venn diagrams. That will at least get the ball rolling.
