For the practical world, generally we seek admittance to a Treasury that is devoid of risk totally. It happens to be the existence of an asset that is devoid of risk, and also plays a vital role, in the prototypical explanation of the subsequent lessons and in all these graphs that depict mean-variance as well. Hence, let us introduce another rate that is devoid of risks which we now call as F in to the scene. Let it be 4%. We shall commence with the three basic portfolios that are given in the following

This is done to make sure of the determining factor of the reward that you get out of this formulation. If the rate of return is to be determined, then the value can be expected to give a variance such as,

This formula proves to be much easier than the comparative ones.

As stated, the risks that are involved are not much and can be easily undone and accounted for the formula values.

You are taught to never rely on random things and in the figure 8.8, you get an even more closer lesson on that.
