Total number of students in the group is n(FuHuC). Let F, H and C represent the set of students who play foot ball, hockey and cricket respectively. Find the total number of students in the group (Assume that each student in the group plays at least one game). In a group of students, 65 play foot ball, 45 play hockey, 42 play cricket, 20 play foot ball and hockey, 25 play foot ball and cricket, 15 play hockey and cricket and 8 play all the three games. Total Number of students who had taken only one course : Number of students who had taken only physics = 22 Number of students who had taken only chemistry = 60 Number of students who had taken only math = 24 Venn diagram related to the information given in the question: Hence, the total number of students who had taken only one course is 106.Īlternative Method (Using venn diagram) : Total number of students who had taken only one course : Number of students who had taken only Physics : Number of students who had taken only Chemistry : Number of students who had taken only Math Let M, C, P represent sets of students who had taken mathematics, chemistry and physics respectively. In a survey of university students, 64 had taken mathematics course, 94 had taken chemistry course, 58 had taken physics course, 28 had taken mathematics and physics, 26 had taken mathematics and chemistry, 22 had taken chemistry and physics course, and 14 had taken all the three courses.
