Answer:
a) 
And replacing we got:

b) 
And then the expected value would be:

Step-by-step explanation:
We assume the following distribution given:
Y 0 1 2 3
P(Y) 0.60 0.25 0.10 0.05
Part a
We can find the expected value with this formula:

And replacing we got:

Part b
If we want to find the expected value of
we need to find the expected value of Y^2 and we have:

And replacing we got:

And then the expected value would be:

Answer:
the average daily balance is 500
Step-by-step explanation:
If a payment of 5,000 is made on the tenth day you can divide 5,000 by ten to get the amount payed everyday before hand. Once you do that you will end up with the answer of 500. Therefore the average daily balance is 500
