This video briefly explains the meaning of discrete probability distributions and introduces the concept of binomial distributions. Discrete probability distribution is a probability distribution characterized by random variables assuming only a finite re-countable number of values. Here, the number of total events is limited. The video exemplifies it through an example of probability associated the sides of a die that could have only 6 outcomes/values. Moving on, the video introduces the concept of binomial distributions-a probability distribution characterized by the random variables assuming either a value for success or a value for failure. Next, the video talks about the requirement of binomial distributions and the impact of random variables. In binomial distributions, there must be a fixed number of trails, can only 2 outcomes of any random variable, the probabilities associated with success or failure must be constant throughout the trails and the result of trials have to be independent with each other.
