In a survey of 480 students, 253 indicated that play the piano, 268 indicated that they play the harp and 73 indicated they play the piano and the harp. How many students surveyed play at least one of these instruments mentioned here?

The no. of students that play at least one instrument = 448

Total number of students surveyed = 480

Students play piano =  253

Students play harp   =  268

Students play both harp & Piano = 73

Thus number of student surveyed that they play at least one of the instrument  = (Students play piano) + (Students play harp) - (Students play both devices)

= 253 + 268 - 73

= 448
