comment Trying to prove Equivalency using Boolean Algebra
Please fix your typo, the equation at the start of your question is not the same as the one in the first line of your answer.

There are 3 diagonals with 4 lights - if you are willing to consider diagonals with less than 4 lights then there are more

The advantage of the Markov chain is it can be extended to answer Question 2. Your idea is much easier for Question 1 - wish I had though of it!

comment Mixed Distributions - Expectation and Variance
Yes - this was a typo on the second last line, didn't affect the final result. Feel free to use a Binomial distribution - you will be wrong but I believe in freedom! Seriously, that is really another question - post it and I will offer a full answer.

Also, if you overcome the issue in my first comment the distribution you need is Poisson - see en.wikipedia.org/wiki/Poisson_distribution

You do not have enough information to solve b) & c) - there is no time given for $p$: is it per day, per year, per lifetime of the bike?
