36 students registered in Math Trail only,
50 students registered in Amazing Race only and
36 students who did not registered in both events.

We have according to question

Total number of students
=150

Number of students in Math Trail
=64

Number of students in Amazing Race
=78

Number of students registered in both
=28

To find: Number of students registered in Math Trail only and in Amazing Race only. And number of students who did not registered in both events.

Now, Number of students registered in Math Trail only


=64-28\\=36

Number of students registered in Amazing Race only


=78-28\\=50

Number of students who did not registered in both events


=56+78-28\\=114\\150-114=36

Therefore
36 students registered in Math Trail only,
50 students registered in Amazing Race only and
36 students who did not registered in both events.
