If f(x)=3x^2+1 and g(x), what is the value of (f-g)(2)?

3(2)^2+1=3(2)^3=24
this is the answer check it out
(please this answer is just only for f(×) since g didn't have a equation this the best I could do and I couldn't subtract from g.)

It is 2 out of 8 she will pick green and 3 out of 7 she will pick green but red and green would be 5 out of 5 so 50% chance

The variables should add up to equal 1
