Chapter 1 Class 11 - Sets - Assertion and Reasoning Worksheet 1 by teachoo Chapter: Chapter 1 Class 11 Maths – Sets Name: _____________________________ School: _____________________________ Roll Number: _____________________________ Instructions: For each question, two statements are given: Assertion (A) and Reason (R). Choose the correct option. (a) Both A and R are true, and R is the correct explanation of A. (b) Both A and R are true, but R is not the correct explanation of A. (c) A is true, but R is false. (d) A is false, but R is true. Assertion (A): The group of "all skilled workers" in a factory is not a well-defined set. Reason (R): The term "skilled" is subjective and lacks a precise, measurable criterion, making the collection not well defined. Assertion (A): The set of ingredients for a cheese pizza, {dough, tomato sauce, cheese}, is equal to the set of ingredients for a "classic pizza," {cheese, dough, tomato sauce}. Reason (R): The order in which elements are listed in a set does not change the set's identity. Assertion (A): In biological classification, the set of all 'Tigers' is a proper subset of the set of all 'Mammals'. Reason (R): Every tiger is a mammal, but there are many other mammals (like elephants) that are not tigers. Assertion (A): An email spam filter places emails into a 'Spam' folder (Set S ). The set of all emails in your main 'Inbox' can be represented as S^'. Reason (R): The complement S^' contains all emails from the universal set of incoming mail that are not in the set S. Assertion (A): If a software program's Version 2.0 (Set V2) has all the features of Version 1.0 (Set V1) plus some new ones, then the set of new features is represented by V2-V1. Reason (R): The difference of sets A - B contains only the elements that are in A but not in B.
