Answer:
<em>There are </em><em>70</em><em> students only in chorus.</em>
Step-by-step explanation:
Total number of students is 250
Out of 250, 180 students took band.
And 60 took band and chorus, i.e this is the intersection of the 2 groups.
The Venn diagram is attached below.
So, the number of students who took only band = 180-60 = 120
Total number of students or sum of the 3 regions is 250.
So, the number of students who took only chorus = 250-180 = 70
