In other cases, we are asked to find the values of one or more variables involved in the model for which the experiment has a given expected value . Example 2: A company makes electronic gadgets.... To maximize his expected profit he should buy just enough to meet his expected demand. So if you could calculate the expected demand you would have the answer. All you actually know though is that the expected demand is greater than 2.6 ( the value you would get if â€¦

**MATLAB how to solve this integral for getting expected value?**

I have a word problem, A game is played where a fair coin is tossed until the first tail occurs. The probability tosses will x tosses will be needed is $ f(x) = 0.5^x;x=1,2,3,4,5$. You win $2^x$... Introduction for solving expected value x: In this topic we will discuss about solving expected value x for discrete chance variable. Expected value is one of the fundamental thoughts in probability, in a sense more general than probability itself.

**Solving for S(t) and E[S(t)] in Geometric Brownian Motion**

Definition (informal) The expected value of a random variable is the weighted average of the values that can take on, where each possible value is weighted by its respective probability.... That means that the expected value of 1 roll, the expected value of the sum of 20 rolls is just 20 times the expected value of 1 roll. The expected value of a roll, let me do it here, expected value of a roll is going to be equal to 67.4 divided by 20. We can get our calculator out. Let's see. So we have 67.4 divided by 20 is 3.37. So this is equal to 3.37. So how does that help us? We know

## How To Solve Expected Value

### The expected value of a random variable X is denoted by Given that the random variable X is discrete and has a probability distribution f(x), the expected value of the random variable is given by:

- Introduction for solving expected value x: In this topic we will discuss about solving expected value x for discrete chance variable. Expected value is one of the fundamental thoughts in probability, in a sense more general than probability itself.
- Expected Value The mean of the discrete random variable X is also called the expected value of X. Notationally, the expected value of X is denoted by E(X). Use the following formula to compute the mean of a discrete random variable.
- To maximize his expected profit he should buy just enough to meet his expected demand. So if you could calculate the expected demand you would have the answer. All you actually know though is that the expected demand is greater than 2.6 ( the value you would get if â€¦
