Step-by-step explanation:
Given : In a sociology class there are 14 sociology majors and 11 non-sociology majors.
Total students = 14+11=25
Number of students are randomly selected = 3
Then, the number of ways to select 3 students from 25 students :-

Number of ways to select at least 2 of the 3 students re non-sociology majors :-

Subtract -3/6 hr
Area of whole - White area = Shaded part
Area of rectangle = l*w
12*15= 180 ( whole)
8*10 = 80 ( white)
Shaded area = 180 - 80 = 100
