The expected rate of return on the stock is 3.65 percent.
To calculate the expected rate of return on the stock, we need to multiply each possible return by its corresponding probability, and then sum the results.
The expected rate of return can be calculated as follows:
- 20% return in a booming economy with a 5% probability: 20% * 0.05 = 1%
- 11% return in a normal economy with a 75% probability: 11% * 0.75 = 8.25%
- -28% return in a recessionary economy with a 20% probability: -28% * 0.20 = -5.6%
Finally, we sum the results: 1% + 8.25% + (-5.6%) = 3.65%
Therefore, the expected rate of return on this stock is closest to 3.65 percent (d).
