A college has four programs B.A., B.Sc., B.Com. and B.B.A. The results of the mid-semester and end-semester tests are shown in the table given below.Results Number of students Β.Α. B.Sc. B.Com. Β.Β.Α. Failed in both tests 28 23 17 27 Failed in mid-semester test but passed in end-semester test 14 12 8 13 passed in mid-semester test but failed in end-semester test 6 17 9 15 Passed in both tests 64 55 46 76
To find the total number of students in the four programs (B.A., B.Sc., B.Com., B.B.A.), we need to sum the counts for all categories within each program and then sum the totals for all programs.
Students in B.A. = Failed in both + Failed mid, passed end + Passed mid, failed end + Passed both
B.A. = $28 + 14 + 6 + 64 = 112$ students
Students in B.Sc. = Failed in both + Failed mid, passed end + Passed mid, failed end + Passed both
B.Sc. = $23 + 12 + 17 + 55 = 107$ students
Students in B.Com. = Failed in both + Failed mid, passed end + Passed mid, failed end + Passed both
B.Com. = $17 + 8 + 9 + 46 = 80$ students
Students in B.B.A. = Failed in both + Failed mid, passed end + Passed mid, failed end + Passed both
B.B.A. = $27 + 13 + 15 + 76 = 131$ students
Total students in all four programs = B.A. Total + B.Sc. Total + B.Com. Total + B.B.A. Total
Total Students = $112 + 107 + 80 + 131 = 430$ students
