Probability analysis

Not really. There was once one question where they gave you the probability of something happening in 1 year and then the probability of something happening in the second year. For example, suppose the probability of getting 100 in the first year was 0.4, and the probability of getting 100 in the second year was 0.3. All you could need to know (but is not to likely) is that to get the probability of both things happening, you multiply the probabilities together. So in my little example, the probability of getting 100 in the first year and also getting 100 in the second year is 0.4 x 0.3 = 0.12

You are welcome :-)
