However, if you have a set of numbers like your X that are sampled from this distribution, the mean of Jungle Wild Slot Machine Online Free numbers estimates E. You are now following this question You will see updates in your activity feed.

And you would also realize components of Portfolio A contains 5 times more risk than the portfolio component B. Standard deviation states the level of variance from the average value.

The formula for different probable returns through which we calculate the expected return for an investment which is calculated in the following steps:.

Step 1 : Initially, we need to determine how much we are going to invest and worth of the investment at the beginning of the investment. Step 3 : Now, calculate the return based on the asset value at each probability at every initial phase and end of the period.

Step 4 : Finally, the expected return of an investment which we obtain at different probable returns is the sum of the product of each probable return and the corresponding probability of given asset.

The various steps by which we can calculate the expected return of portfolio which is an extension of the expected return of investment, here we give more emphasis on the weighted average of returns of each investment in the portfolio and it is calculated as follows:.

Step 1 : Initially, we need to determine an amount which we are going to invest at the start of the period. Step 2 : In the next step, we need to determine the weight of each asset form the portfolio which is denoted as w.

Step 3 : Finally, the expected return of a portfolio with varying returns is calculated as a sum of the product of varying returns of each of the asset form the portfolio along with their respective weight as specified below:.

Expected return plays a vital role in determining the overall return of the portfolio, it is widely used by the investors to anticipate the profit or loss may have while investing in it.

Based on the expected return formula an investor can decide whether he should continue to remain invested in the given probable returns. If you play this game many times, will you come out ahead?

Suppose you play a game with a spinner. You play each game by spinning the spinner once. Complete the following expected value table. Like data, probability distributions have standard deviations.

Add the last column in the table. The standard deviation is the square root of 0. Toss a fair, six-sided die twice. Tossing one fair six-sided die twice has the same sample space as tossing two fair six-sided dice.

The sample space has 36 outcomes:. Use this value to complete the fourth column. On May 11, at PM, the probability that moderate seismic activity one moderate earthquake would occur in the next 48 hours in Iran was about Suppose you make a bet that a moderate earthquake will occur in Iran during this period.

If you bet many times, will you come out ahead? Explain your answer in a complete sentence using numbers.

What is the standard deviation of X? Construct a table similar to the one in Example 5 to help you answer these questions.

On May 11, at PM, the probability that moderate seismic activity one moderate earthquake would occur in the next 48 hours in Japan was about 1.

As in Example 6, you bet that a moderate earthquake will occur in Japan during this period. Find the mean and standard deviation of X.

Some of the more common discrete probability functions are binomial, geometric, hypergeometric, and Poisson. Most elementary courses do not cover the geometric, hypergeometric, and Poisson.

Your instructor will let you know if he or she wishes to cover these distributions. A probability distribution function is a pattern. These distributions are tools to make solving probability problems easier.

Each distribution has its own special characteristics. Learning the characteristics enables you to distinguish among the different distributions.

Class Catalogue at the Florida State University. The expected value, or mean, of a discrete random variable predicts the long-term results of a statistical experiment that has been repeated many times.

Based on the given information, help Ben to decide which security is expected to give him higher returns. In this case, the expected value is the expected return of each security.

Let us take another example where John is to assess the feasibility of two upcoming development projects Project X and Y and choose the most favorable one.

Determine for John which project is expected to have a higher value on completion. It is important to understand for an analyst to understand the concept of expected value as it is used by most investors to anticipate the long-run return of different financial assets.

The expected value is commonly used to indicate the anticipated value of an investment in the future. On the basis of the probabilities of possible scenarios, the analyst can figure out the expected value of the probable values.

Although the concept of expected value is often used in the case of various multivariate models and scenario analysis, it is predominantly used in the calculation of expected return.
