Marcus randomly draws tokens from a bag containing 10 blue tokens, 8 green tokens, and 12 red tokens. The first draw is a green token. What is the probability of this event?

4/11
4/15
1/2
1/3

The probability of drawing a green token on the first draw is equal to the number of green tokens divided by the total number of tokens in the bag.

There are 8 green tokens in the bag and a total of 10 blue + 8 green + 12 red = 30 tokens in total.

Therefore, the probability is 8/30, which can be simplified to 4/15.

So the correct answer is 4/15.
