Answer:

2/13

Step-by-step explanation:

There are 6 + 4 + 3 = 13 balls all together.

If the first one is green, this will happen with a probability of 4/13. Now there are 12 balls left

There are 6 red balls. 6/12 = 1/2

The probability of the way this happens is 1/2 * 4/13 = 2/13

The answer is D. 2^6.

Because you re basically doing:

2*2*2*2*2*2

And if you multiply all of it, it will equal 64.

Hope this helps!
