On an engine, the timing chain has colored links, and you have to line up these colored links on timing marks on the engine. There's typically marks on sprockets, bearing caps, gears.
A understand that you have to line these up in order to get proper timing. I understand that is the reason why...

To approach this, I first assumed the case when the students attempts all the remaining questions.
Probability that they gain 4 marks for a guess = ##\frac 1 4##
Probability that they lose 1 for a guess = ##\frac 3 4##
Now let us say the number of correct guesses = ##r##
Now we should have at...
