<span>The correct answer is 1/78.

Explanation<span>:
There are 2 orange marbles out of 13 total marbles, so the probability of your first marble being orange is 2/13.

After this one is drawn, since it is not returned, the probability of getting a second orange marble is 1/12, since there is only 1 orange marble left out of 12 total marbles.

This gives us the total probability 2/13(1/12)=2/156=1/78.</span></span>

F(x) = 3x-1 and g(x)=2x^2
Law Incorporation [45]

Answer:

See below

Step-by-step explanation:

a.  here you are to multiply the two functions together:

(3x-1)(2x^{2} )=6x^{3}-2x^{2}

b.  here you are to subtract g from f:

(3x-1)-(2x^{2})=-2x^{2}+3x-1

c.  here you are to compose g into f.  In other words, pick up the whole g function and plug it into f wherever you see an x:

3(2x^{2} )-1=6x^{2} -1

d.  here you are compose f into g.  In other words, pick up the whole f function and plug it into g wherever you see an x:

2(3x-1)^2

You now have to FOIL out the (3x-1) like so:

2[(3x-1)(3x-1)]

which gives you

2(9x^{2} -6x+1)

Distribute in the 2 and you'll end up with the answer:

18x^{2} -12x+2
