Find the probability of drawing a green card, not replacing it, and then drawing another green card. 9 100
3 50
1 15

1/15

Step-by-step explanation:

This is probably too late but I'll do it anyway.

There are 10 cards in all.

of the 10, 3 are green.

So your chance of drawing the first green is 3/10

Now you have 9 cards in total left.

Two of them are green

Your chance of drawing a green card again is 2/9

Your total chance of drawing 2 green cards is

2/9 * 3/10 = 6/90

2/9 * 3/10 = 1/15

Step-by-step explanation:

The standard form of a circle is

(x-h)^2+(y-k)^2=r^2

where (h,k) is the center and r is the radius, therefore

(x-3)^2+(y-5)^2=4 must be the answer
