So probability will be 0.34
Step-by-step explanation:
We have given that a university admitted 100 students
In which 34 students are from two year community program
25 students are from private four year institution
And rest that is 100-34-25 = 41 students from public four year institutions
Number of ways for selecting two students from two year community program that is, from 34 students

And the number of ways in selecting the 2 students from total student 
So probability will be 
Answer:
The three numbers are : 9, 9 and 18
Step-by-step explanation:
Since the mean is 12 the sum of the three numbers must be 36. This is because:
(let the three numbers be x y and z)
(x+y+z)/3=12
(x+y+z)=12*3
(x+y+z)=36
And since the mode is 9 two of the numbers must be 9.
So to find the third number;
9+9+z=36
z=36-18
z=18
