$2100.

Step-by-step explanation:

We have been given that a real estate agent spends $1,500 on advertising for three months to sell an average house. This means that cost of advertisement is $1500.

We are also told that if he house sells in three months, the agent earns $9,000 and there is a 40% chance that he will sell the house in three months.

To find the expected revenue first of all let us find 40% of $9000.

Therefore, the expected revenue for the real estate agent is $2100, is he sells the house in 3 months.
