Total students = 15+21=36, so the probability of choosing a girl is 21/36, which reduces to 7/12.
Total freshmen = 12+15=27, so the probability of choosing a freshman is 27/36, which reduces to 3/4.

Answer:
Natasha gets 84
Step-by-step explanation:
Here, we want to know how much Natasha gets
Krutika gets 2 times as much as Natasha
If Natasha gets x, Krutika gets 2x
If Natasha gets x, Richard will get x/3 ( 3 times of this is what Natasha gets)
Now let us have a ratio;
K : N : R
2x : x : x/3
Multiply through by 3
6x : 3x : x
To get the amount Natasha gets, we add up all ratio; (6x + 3x + x ) = 10x
Natasha gets 3x of the total ratio
That will be;
3x /10x * 280
= 3/10 * 280
= 84
