4. Random Variables • Many random processes produce numbers. These numbers are called random variables. Examples (i) The sum of two dice. (ii) The length of time I have to wait at the bus stop for a #2 bus. (iii) The number of heads in 20 ?ips of a coin. De?nition. A random variable, X, is a function from the sample space S to the real numbers, i.e., X is a rule which assigns a number X... Random Variables and Probability Distributions (Page 4 of 23) Exercise 7 Data was collected over 208 nights tabulating the number of room calls in a night requiring a nurse.

**Solution 7 Problem 1 Generating Random Variables**

Probability Distributions?Semester II Page 2 then X and Y are said to be independent random variables. 1.2 SOLVED PROBLEMS Problem 1 If X and Y are discrete rv’s with the joint probability function is B (x,y) = e > 6 i 5 <, where (x,y) = (1, 1), (1,2), 2, 1), (2, 2) = 0 , else where. Are the variable independent. Solution : Given B(x,y) = e > 6 i 5 <, where (x,y) = (1,1), (1,2), (2... probability distributions: P(x,y), where X and Y are two random variables. These have the obvious interpretation that P(x,y) dx dy = probability that X is the range x to x+dx while simultaneously Y is in the range y to y+dy. This can trivially be extended to multiple variables, or to the case where one or more variables are discrete and not continuous. Normalization condition still applies

ECE302 Spring 2006 HW5 Solutions February 21, 2006 3 Problem 3.2.1 • The random variable X has probability density function fX (x) = ? cx 0 ? x ? 2,... could anyone please indicate a general strategy (if there is any) to get the PDF (or CDF) of the product of two random variables, each having known distributions and limits? After having scanned related questions, I suspect there is no general strategy and the solution will depend on the distributions.

**Joint Probability and Bivariate Distributions**

The abbreviation of pdf is used for a probability distribution function. Solution: In this case, the random variable is x = number of people in a household. This is a discrete random variable, since you are counting the number of people in a household. Chapter 5: Discrete Probability Distributions 158 This is a probability distribution since you have the x value and the probabilities that... a State, giving reasons, whether each of the following represents a discrete probability distribution. i ii iii b A random variable, X, has the following probability distribution.

- Discrete random variables are obtained by counting and have values for which there are no in-between values. These values are typically the integers 0, 1, 2, …. Random variables are usually denoted by upper case (capital) letters. The possible values are denoted by the corresponding lower case letters, so that we talk about events of the form [X = x]. The random variables are described by
