【正确答案】 B

【答案解析】每个选项的期望货币价值等于每个预计现金流入乘以他们相应的概率，再进行加总。 选项 1的期望货币价值 = $50,000(0.1) + $75,000(0.2) + $100,000(0.4) + $150,000(0.3) = $105,000 选项 2 的期望货币价值 = $50,000(0.1) + $75,000(0.2) + $100,000(0.45) + $150,000(0.25) = $102,500 选项 3的期望货币价值 = $50,000(0.1) + $75,000(0.2) + $100,000(0.4) + $125,000(0.3) = $97,500 选项 4 的期望货币价值 = $150,000(0.1) + $100,000(0.2) + $75,000(0.4) + $50,000(0.3) = $80,000
