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 `n=5,p=0.75` the value of `P(E//F)gelamda`, then `lamda` can be

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

A multiple - choice question has 5 options of which only one is correct. If a student does home work, then he is sure to identify the correct answer, otherwise the answer is chosen at random. Let A ne the event that the student does his home work and B be the event that the student answers correctly. If P(A)=(2)/(3) , then P((A)/(B)) is euqal to

A multiple choice test question has five alternative answers, of which one is home work, then he is sure to identify the correct answer; otherwise, he chooses Let E: denotes the event that a student does his home work with P(E)=P and F: denotes the event that he answer the question correctly. (a) If p=0.75 the value of P(E/F) equals

If E and F are events with P(E) 0 then which one is not correct?

A student answers a multiple choice question with 5 alternatives, of which exactly one is correct. The probability that he knows the correct answer is p, 0 lt p lt 1 . If he does not know the correct answer, he randomly ticks one answer. Given that he has answered the question correctly, the probability that he did not tick the answer randomly, is

A multiple choice emamination has 5 questions. Each question has three alternative answers of which exactly one is correct. The probability that a student will get 4 or more correct answers just guessing is
