Answer:
The sets has more than 150 students
P∪A∪M
-(P∩A)
Step-by-step explanation:
See the attached figure which represents Venn diagram for the question:
180 take PE
80 take art
72 take music
33 take PE and art
28 take PE and music
20 take all three
M= all students taking music
A= all students taking art
P= all students taking PE
Number of students taking PE and art only = 33 - 20 = 13
Number of students taking PE and music only = 28 - 20 = 8
Number of students taking PE only = 180 - (20 + 13 + 8) = 139
Number of students taking ARt only = 80 - (20 + 13) = 47
Number of students taking Music only = 72 - (20 + 8) = 44
Number of students doesn't take any thing =
300 - (20 + 13 + 8 + 139 + 47 + 44) = 29
We will check the options to find the sets has more than 150 students:
1) A∪M = 13 + 47 + 20 + 8 + 44 = 132 < 150
2) P∩M = 20 + 8 = 28 < 150
3) P∩A∩M = 20 < 150
4) P∪A∪M = 20 + 13 + 8 + 139 + 47 + 44 = 271 > 150
5) -(P∩A) = 300 - (13+20) = 267 > 150
So, The sets has more than 150 students
P∪A∪M
-(P∩A)
