A discrete random variable is a variable that can only take on a finite or countable number of distinct values
A discrete random variable is a variable that can only take on a finite or countable number of distinct values. Here are some examples of discrete random variables:
1. Tossing a coin: The outcome of a coin toss can be either heads or tails, making it a discrete random variable. The probability of getting heads would be 0.5 and the probability of getting tails would also be 0.5.
2. Rolling a die: The outcome of rolling a fair six-sided die can be the numbers 1, 2, 3, 4, 5, or 6. Each number has an equal probability of 1/6.
3. Number of siblings: The number of siblings a person has is a discrete random variable because it can only take on whole number values, such as 0, 1, 2, 3, and so on.
4. Number of cars in a parking lot: If you count the number of cars in a parking lot, you would get a discrete random variable since you can only count whole numbers. For example, the number of cars might be 10, 15, or 20.
5. Number of students in a class: The number of students in a class is also a discrete random variable because it can only take on whole number values. For instance, the number of students might be 20, 25, or 30.
It’s important to note that for each of these examples, the probabilities associated with the outcomes must add up to 1. Additionally, the probabilities must be between 0 and 1.
