Answer:
13/48
Step-by-step explanation:
If we add the number students who play only, who know play piano and who
do not play both we get 35 students.
Remaining students : 48-35 = 13
Probability of students who play both the instruments = 13/48
Assuming that these students may know to play both the instruments as the information about 13 students was not given.
