We have also studied about random variables and their probability distributions, namely binomial distribution and Poisson distribution.
The binomial distribution is defined on a random variable which takes finite discrete values whereas the Poisson distribution is defined on a random variable which takes infinite discrete values such as 0, 1, 2, 3, ….There are few more discrete probability distribution which will be discussed in higher classes. The most important continuous probability distribution in the entire field of statistics is normal distribution. This bell shaped probability distribution function is also an approximate to binomial distribution. We will be learning the importance of these distribution function in later classes.
