You are given that:
-
The course COMP 9999 runs over a period of one year, starting on January 1 and ending on December
31. There is one lecture every day; thus, the total number of lectures is 365.
-
At the beginning of each of the 365 lectures, Nick flips a fair and independent coin twice.
If the coin comes up heads twice, then Nick eats 3 bananas during the lecture; otherwise,
Nick eats 5 bananas during the lecture.
Let $X$ be the total number of bananas that Nick eats during the 365 lectures of the course COMP
9999. What is the expected value $\mathbb{E}(X)$ of $X$?
(n.b., you may find it useful to apply Linearity of Expectation)
