Midterm exam: Clarifications/Answers to questions.

General: The amount of calculations needed in the different subproblems in the exam are not equal. Some subproblems require only one line of calculations, others require substantially more.

1.5 You are not allowed to use sympy. Of course you can check your calculations with sympy, but the calculations should be analytical with justifications for each step, so we can see what you have done. Neglect the tau neutrino in this subproblem.

1.6 You may interpret the ratio 1/10000 to mean that the probability of detecting a muon neutrino is 1/10000.  "Far away" means "an unspecified distance". "a limit" means "a lowest upper bound or a greatest lower bound". Only one of these bounds can be deduced here when you dont know the distance nor the neutrino velocity. Neglect the tau neutrino in this subproblem.
