the marginal pmf’s (pdf’s). Example 8 If X 1 ;¢¢¢ ;X n represent the lifetimes of n independent compo- nents, and each lifetime is exponentially distributed with parameter ‚ .... The following two formulas are used to find the expected value of a function g of random variables X and Y. The first formula is used when X and Y are discrete random variables with pdf f(x,y). The first formula is used when X and Y are discrete random variables with pdf f(x,y).

Introduction Value at risk (VaR) is today the standard tool in risk management for banks and other how to algebraically find the zeros expected value 9 Expected Utility • Individuals do not care directly about the dollar values of the prizes – they care about the utility that the dollars provide • If we assume diminishing marginal utility of wealth, the St. Petersburg game may converge to a finite expected utility value – this would measure how much the game is worth to the individual 10 Expected Utility • Expected

- For a continuous random variable, the expected value of an arbitrary function of the random variable g(X) is given by Expected Value of Joint Random Variables For a pair of random variables X and Y with a joint probability distribution f(x,y), the expected value can be found by use of an arbitrary function of the random variables g(X,Y) such that

- Notes for Math 450 Lecture Notes 3 Renato Feres 1 Moments of Random Variables We introduce some of the standard parameters associated to a random variable. The two most common are the expected value and the variance. These are special cases of moments of a probability distribution. Before deﬁning these quantities, it may be helpful to recall some basic concepts associated to random variables
