Answer:
I would advice to invest on the direct portfolio as yield the better expected return with the current information.
Step-by-step explanation:
When an investment outcome can vary, we multiply the outcome by the probability:
direct portfolio
0.05 x 20,000 = 1,000
0.60 x 15,000 = 9,000
0.30 x 10,000 = 3,000
0.05 x 4,000 = 200
Expected return 13,200
HIgh risk stock
0.01 x 100,000 = 1,000
0.99 x 0 = 0
Expected return 1,000
For the other two option the retun is "safe"
do nothing: 5,000
guaranteed interest: 9,000
The best outcome will be of the direct portfolio as the expected return is higher than other option: 13,200
