A multiple choice question has n options...

A multiple choice question has `n` options, of whlch only one is correct. If a student does home work, then it is sure to identify the correct answer, otherwise answer is choosen at random. Let `E` be the event that student does home work with `P(E)=p` and `F` be the event that student answers question correctly
If the largest set of values of `p` for which relaton `P(E//F)geP(E)` holds is `[a,b]` then
