Final answer:
The company can expect to gain $60,622 in the housing project.
Step-by-step explanation:
To calculate the expected gain or loss, we can multiply the probabilities of each outcome by their respective values and sum them up.
For the housing project:
The expected gain or loss = (30% * (-$236,016)) + (30% * (-$148,803)) + (40% * $440,171) = -$70,804.80 + (-$44,641.20) + $176,068.40 = -$70,804.80 - $44,641.20 + $176,068.40 = $60,622
Therefore, the company can expect to gain $60,622 in the housing project.
