Chapter 5: Probability Distributions
What you need to learn in this chapter
In this chapter, we will be learning about probability distributions.
We will start by understanding the concept of a random variable, which is a variable that takes on different values based on the outcome of a random event.
We will then explore the binomial distribution, which is used to calculate the probability of a specific number of successes in a fixed number of independent trials.
Next, we will delve into the normal distribution, which is a continuous probability distribution that is often used to model real-world phenomena.
Throughout this chapter, we will also compare and differentiate between discrete random variables, which can only take on certain values, and continuous random variables, which can take on any value within a range.
