the neither = 13 , the minimum number of students in any or both = 15 , thus 19 is out
the maximum number of students (given 13 is in neither ) in any or both could reach = 25 thus 42 and 46 are out
now the answer is b or c both could be the answer??
if the intersection between the 2 groups = 0 thus total = 13+15+10 = 38
if the intersection between the 2 groups = 4 thus total = 15+6+13 or 11+10+13 = 34
