A question paper has 5 questions. Each question has an alternative. The number of ways in which a student can attempt atleast one question is

A question paper contains 6 question each having an alternative . The number of ways that an examine can answer one or more question is

Assertion (A) : A question paper contains 5 questions each having an alternative. The number of ways that an examinee can answer one or more questions is 242. Reason (R): The number of ways of answering one or more of n questions when each question have an alternative is 3^(n)-1 . The correct answer is

Eight questions are given , each question has an alternative Prove that the number of ways in which a student can select one or more Questions is (2^(8)-1) .

There is a question paper consisting of 15 questions. Each question has an internal choice of 3 options. In how many ways can a student attempt one or more questions of the given fifteen questions in the paper?

In an examination of Mathematics paper,there are "20" questions of equal marks and the question paper is divided into three sections : "A,B" and "C". A student is required to attempt total "15" questions taking at least "4" questions from each section.If section "A" has "8" questions,section "B" has "6" questions and section "C" has "6" questions, then the total number of ways a student can select "15" questions is
