What is the variance of returns of a portfolio that produced returns of 20%, 25%, and 30%, respectively

16.7

Explanation:

Calculation for What is the variance of returns of the portfolio

First step is to calculate the mean

Mean = (20% + 25% + 30%) / 3

Mean =75% / 3

Mean = 25%

Now let calculate the variance of returns of the portfolio

Portfolio variance of returns = {(20 − 25)^2 + (25 − 25)^2 + (30 − 25)^2} / 3

Portfolio variance of returns=25+0+25/3

Portfolio variance of returns=50/3

Portfolio variance of returns= 16.7

Therefore the variance of returns of the portfolio will be 16.7

being born in poverty would limit the people's chances, opportunities and benefits.

this happen because of several things, such as:

- poor people tend to gain less access to good education and nutrition. this mean that their chance to obtain high paying jobs would also be limited.

- poor people tend to socialize with other poor people while the rich tend to socialize with other rich people. this means that simply throguh their social circle, rich people would have more business opportunities compared to the poor people.

- rich people tend to have more capital in their disposal. this would benefit them in business since it is far easier for them to fund their business operation compared to poor people.
