#### Solution Preview

In case of less risky expected return, spread (variance) is low i.e. probability distribution is peaked. If the riskiness is further reduced, variance further decreases and it becomes ...

#### Solution Summary

Shape of probability distribution of returns is influenced by the riskiness of a security. Solution discusses the shape of probability distribution of returns in the two extreme given cases.
