判断正误
1。Having half of two risky assets is always better than having only one of them.
2。A risk lover agent will always invest his / her wealth in the risky asset when the alternative is risk free.
3。If an economic agent invests in equal proportion in a very large number of uncorrelated assets, the risk he /she faces tends to vanish.
判断后请稍微做些解释。谢谢!
