There are 48 questions in a test.Each correct answer fetches 1 mark,for each wrong answer (1)/(2) mark is deducted.A student got 21 marks by attempting all questions.The number of questions answered wrongly is

In a multiple choice question there are 4 alternative answers of which 1, 2, 3, or all may be correct. A candidate will get marks in the question only if he ticks all the correct answers. The candidate decides to tick answers at random. If he is allowed upto 5 chances to answer the question, the probability that he will get the marks in the question is
