Document Summary
Frequency theory- works best for processes which can be repeated over and over again, independently and under the same conditions. The chance of something gives the percentage of time it is expected to happen, when the process is done over and over again, independently and under the same conditions, between 0 and 100%. The chance of something equals 100% minus the chance of the opposite thing. Conditional probabilities the result of the first event places a condition upon the subsequent event(s) Multiplication rule- the chance that two things will both happen equals the chance that the first will happen, multiplied by the chance that the second will happen given that the first has happened. Independence two things are independent if the chances for the second given the first are the same, no matter how the first one turns out. If two things are independent, the chance that both will happen equals the product of their unconditional probabilities.
