One way you could solve this is to just multiply the top and bottom out so that you get 9/81, reducing it by 9/9 to get 1/9 or option C.
Another way would be to do

since dividing numbers with exponents would be subtracting the bottom exponent from the top exponent, provided that the base number (in this case 3) is the same for both. For this method, you would get

, which is equal to 1/9 or .1 repeating, the same answer that you'd get with the first method.
(1,2)
The solution is where the lines intersect so you can see they intersect at (1,2)

Answer:
The value is 
Step-by-step explanation:
From question we are told that
The number of types of marbles present jar is n = 3
Generally the probability of drawing a green marble is

Generally the probability of drawing a marble that is not green is

From the question we are told that there will be continuous drawing of marbles from the jar (in such a way that after each marble is drawn it is being replaced) until a green marble drawn
Let m be the number of times marbles has been drawn when a green marble was gotten
it then means that for m - 1 times the marbles where drawn a green marble was not obtain.
Generally the probability drawing m times is mathematically is mathematically represented as

=>
