एउटा माध्यमिक विद्यालयका कक्षा X का 20 जना विद्यार्थीहरूमाभ्र एउटा सर्वेक्षण गरियो । जसमा 14 जनाले फुटवल र 12 जनाले भलिवल खेलमा भाग लिएछन् । प्रत्येक विद्यार्थीले कम्तिमा एउटा खेलमा भाग लिएका रहेछन् ।
A survey was conducted among 20 students of a Secondary School of class X, where 14 students participated in football and 12 students in volleyball game. Every student have participated in at least one game.
a) फुटवलमा भाग लिने विद्यार्थीहरूको समूहलाई F र भलिवलमा भाग लिने विद्यार्थीहरूको समूहलाई V मानी फुटवल अथवा भलिवलमा भाग लिने विद्यार्थीहरूको समूहलाई गणनात्मकता संकेतमा लेख्नुहोस् ।
Assuming the set of students who participated in football as F and volleyball as V, write the cardinality of set of students who participated in volleyball or football.
b) माथिको तथ्यलाई भेन चित्रमा प्रस्तुत गर्नुहोस् ।
Present the above information in the Venn diagram.
c) भेन चित्र प्रयोग गरी एउटा मात्र खेलमा सहभागी हुने विद्यार्थीको सङ्ख्या पत्ता लगाउनुहोस् ।
Find the number of students participating in exactly one game by using Venn diagram.
d) अस्वस्थताका कारणले 2 जना फुटवल मात्र खेल्छौ भनेका खेलाडीले सहभागिता नजनाउँदा कुन समूहको गणनात्मकतामा के असर पर्छ ? कारणसहित लेख्नुहोस् ।
If two students who response only football are unable to play the game due to health problem, the cardinality of which set is changed? Give reason.
