Answer:
Average expected rate of return = 12.5% (Approx)
Explanation:
Given:
Cost of assets = $120
In condition 1 = 25% chance that it will be worth $90
In condition 2 = 25% chance that it will be worth $130
In condition 3 = 50% chance that it will be worth $160
Computation:
Average expected rate of return = Probability (Net worth - Cost of assets) / Cost of assets
Average expected rate of return = [25%($90 - $120) / $120] + [25%($130 - $120) / $120] + [50%($160 - $120) / $120]
Average expected rate of return = [0.25(-$30) / $120] + [0.25($10) / $120] + [0.50($40) / $120]
Average expected rate of return = [-0.0625] + [0.020833] + [0.167]
Average expected rate of return = 0.12533
Average expected rate of return = 12.5% (Approx)
