It is especially helpful for calculating the probabilities of intersections, such as P(A|B), which themselves are critical for the useful Partition Theorem. Additionally, the whole field of stochasti ...

Some Rules of Probability
... What is special and interesting about the above result is that P (H) and P (H|J ′) both equal 0.70. Moreover, one can show that P (H|J) is also equal to 0.70. Thus, the probability of event H is the same regardless of whether or not event J has occurred, occurs, or will occur, and we say that event ...

Random Variables
... within some interval is a possible value. A more readably defining difference would be that discrete random variables are counted and continuous random variables are measured. For instance, the number of beer bottles in a case of beer is discrete, but the volume of ounces is continuous (examine each ...
