Question 987765
.
How many students plan to attend at least one event?


Obviously,  it is  62 + 38 = 100  minus those  15  students who plan to attend both events and whom we counted twice in this sum.  It is  100 - 75 = 85  students.


The rest of  85  students plan to attend neither event.  Their number is  112 - 85 = 27. 


<B>Answer</B>. &nbsp;27 students plan to attend neither event.
