Here is my question:

If it rains a person sells umbrellas and earns $65. If it does not rain then the person either washes cars or goes to the race track. The person washes cars on 80% of the days when it does not rain and earns $125 a day. However, $485 a day is lost when the person goes to the race track. If the probability of rain is .2, what is the person's expected (mean) income? (HINT: You will have to construct a probability distribution to answer this question.)

Thank you in advance for whoever helps .
