Probability Distribution
The word " Probability " often comes into our day-to-day life referring to, " What is the probability of some random event ? " simply saying what at most chance the event to occur. In the last two blogs " The Axioms - Probability " and " What is the probability you will open this blog ? " we see how probability arises over time. But the question is if the event space contains more than some finite or infinite elements, How will we calculate the probability? Here the role of Probability Distribution came into the story. So instead of calculating, we evaluate how the probability is distributed over the region. First, take the simplest example, " Tossing a coin ", so by the axioms of probability we have here two event spaces called head and tail. The probability of getting the head is 1/2 and the same for the tail. For probability distribution let - < X < denotes the entire event
