Suppose a fair die is rolled ten times. Find numerical values for the expectations of each of the following random variables.

a) The sum of the numbers in ten rolls;

b) The sum of the largest two numbers in the first three rolls;

c) The maximum number in the first five rolls.

I believe I figured out part a to be 35.

However, the next two parts of the equation I am completely stuck on. If someone could give me some detailed instructions on what I need to do it would really help me out for the test. Thank you so much.
