The number of ways you can pick 3 people from 9 = 9*8*7 / 3*2*1 = 84
So chance of picking the 3 suspects = 1 / 84.
The number of ways to pick 3 from the 6 innocent people = 6*5*4 / 3*2*1 = 20
Chances of picking 3 innocent people = 20 / 84 or 5/21
Answer:

Answer:
c=93
Step-by-step explanation:
35+3(x+2)+52=180
87+3(x+2)=180
87+3x+6=180
93+3x=180
3x=180-93
3x=87
x=87/3
x=29
3(29+2)
3(31)=93
