Answer:
$6,000.
Step-by-step explanation:
Expected profit is the profit that an investor is expecting (anticipating) to receive from a security. It tells the investor how much of return on average will he generate from a security by taking different scenarios into account. The expected profit is calculate as:

where
E(R) = Expected profit
R = Profit
P = Probability
i = Each respective scenario
The formula takes each profit and multiply it with the respective probability (chance), and the add up the results of all the scenarios.
⇒ Expected profit = [(30,000 * .2) + (10,000 * .6) + (-30,000 * .2)]
OR Expected profit = 6,000 + 6,000 - 6,000 = $6,000.
It means that the investor is expecting that the stock will generate a profit of $6,000 on average.
