**Chapter 2. Continuous random variables**

A random variable is called a discrete random variable is piece-wise constant. Thus is flat except at the points of jump discontinuity. If the sample space is discrete the random variable defined on it is always discrete. X is called a continuous random variable if is an absolutely continuous function of x. Thus is continuous everywhere on and exists everywhere except at finite or countably... Discrete random variables are variables that are a result of a random event. For example, the roll of a die. Discrete random variables are represented by the letter X and have a probability distribution P(X). If you flipped a coin two times and counted the number of tails, that’s a discrete random variable. It’s represented by the letter X. X in this case can only take on one of three

**Chapter 2. Continuous random variables**

Example: Consider a continuous random variable X whose domain is [x,x] so that its density is positive over [ x , x ]. For x a < b x , does strict inequality between a and b …... A random variable is represented by “x” and it is the result of the discrete or continuous probability. A discrete probability is a random variable that can either be a finite or infinite of countable numbers.

**Chapter 2. Continuous random variables**

A random variable is represented by “x” and it is the result of the discrete or continuous probability. A discrete probability is a random variable that can either be a finite or infinite of countable numbers.... If a random variable is a continuous variable, its probability distribution is called a continuous probability distribution. A continuous probability distribution differs from a discrete probability distribution in several ways.

**Chapter 2. Continuous random variables**

Example of discrete random variable Exercise 2.4.1 For a random variable X that takes values {0,1} with probabilities ?,1??, obtain P(X ? x) for all x ? 0 and plot the cumulative distribution function. P(X ? x) = 0 if x < 0 ? if 0 ? x < 1 1 if x ? 1. Continuous random variable When the outcome of an experiment is a measurement on a continuous scale, such as ozone level... If a random variable is a continuous variable, its probability distribution is called a continuous probability distribution. A continuous probability distribution differs from a discrete probability distribution in several ways.

### a discrete random variable can be obtained from the distribution function by noting that (6) where the function f(x) has the properties 1. f(x) 0 2. It follows from the above that if Xis a continuous random variable, then the probability that X takes on any one particular value is zero, whereas the interval probabilitythat X lies between two different values,say,aand b, is given by P(a X b

- A random variable is represented by “x” and it is the result of the discrete or continuous probability. A discrete probability is a random variable that can either be a finite or infinite of countable numbers.
- A continuous random variable can take any value in an interval or collection of intervals. 2. A discrete random variable can take one of a countable list of distinct values. Notation for either type: X, Y, Z, W, etc. 4 1. Couple plans to have 3 children. The random circumstance includes the 3 births, specifically the sexes of the 3 children. Possible outcomes (sample space): BBB, BBG, etc. X
