A marble is drawn at random from the bag shown below. The bag contains 3 green, 4 yellow, 5 blue, and 8 pink marbles.

Im kind of confused, I'm assuming it's talking about how many are pink.

There's 20 marbles in total, and there's 8 pink marbels.

20 divided by 8 = 2.5

2.5 = 2/5

2/5 (If it's talking about how many are not yellow then the answer would be 4/5)

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
