WebbIn probability theory, an event is an outcome or defined collection of outcomes of a random experiment. Since the collection of all possible outcomes to a random experiment is called the sample space, another definiton of event is any subset of a sample space. For example, on the roll of a die, getting an even number is an event. WebbAs we have seen, the probability of a continuous random variable at a particular value is always zero. Therefore for continuous variables, we find the amount of change in CDF at any instance. This change is called the Probability Density Function. In terms of calculus, PDF is the differential of CDF.

WebbProbability is a mathematical tool used to study randomness. It deals with the chance (the likelihood) of an event occurring.

The logarithm of a probability is non-positive. Multiplying the logarithm of a probability with a probability doesn’t change the sign. The sum of non-positive products is non-positive. And finally, the negative of a non-positive value is non-negative.
