In doing so we parallel the discussion of expected values for discrete random variables given in Chapter 6. Based on the probability density function (PDF) description of a continuous random variable, the expected value is defined and its properties explored. The discussion is conceptually much the...
For a discrete random variable X, the expected value of an arbitrary function is given by Example 4: Given that X is a continuous random variable whose PDF is given by find E[g(X)] given that g(X) = 3x2 Solution: For a continuous random variable, the expected value of an arbitrary...
Forsomeproblemswearegiventheprobability and want to find some value that accomplishes that probability. For example • To find a 100*p th percentile or quantile Q(p), solve F(x) = p. o Lifetimes of motors are Weibull with α=10 years and β=2. Find the 50 ...

Given that we know for sure that this is a lower probability than the true value of a coin toss, this bet would then be +EV as we’re getting better odds than it should be. The flip side is that, if the bookmaker were to offer odds of -120 on the coin flip, it would create ...
I would like to find the expected value of a random variable given a distribution and a constraint. For example, given a normal distribution, what is the expected value of x with the constraint that x > 0. The unconditional expected value would be x...
Let X~B(n,p) then the mean or expected value of r. v. X is denoted by E(X) and is given by μ=E(X)=npq. True or False View Solution Find the expected value ,variance and standard deviation of random variable X whose probability mass function (p.m.f.) is given below. View...
ARK’s updated open-source Tesla model yields an expected value per share of $2,000 in 2027. The bull and bear cases, tuned to the 75th and 25th percentile Monte Carlo outcomes, respectively, are approximately $2,500 and $1,400 per share, as shown below.[1] ARK’s Simulation Outputs...
