Mark, evan, and cayla are playing a game. there are 3 blue marbles, 2 red, and 1 green marble. if mark pulls a blue marble he gets $1. if evan pulls a red marble, he gets a $2. if cayla pulls a green marble, she gets $3. is this a fair game? if not, who has the advantage?

To determine whether it is a fair game, you need to find the expected value for every person. In this game, there is 3 blue marbles, 2 red marbles and 1 green marbles so the total marbles would be: 3+2+1 = 6 marbles. The expected value for 

Mark= 3/6 * $1= $0.5
Evan= 2/6 * $2= $2/3= $0.66
Cayla= 1/6 *$3= $0.5

The game is not fair because Evan has higher expected value, thus having an advantage compared to Mark or Cayla

17%, 0.175, 2/11, 1/5 is correct.

Step-by-step explanation:

We can solve this question through options :-

(i) 15 = 15, 2/11 = 0.18, 0.175, 17% = 0.17 (×)

(ii) 2/11 = 0.18, 17% = 0.17 , 0.175, 1/5 = 0.2 (×)

(iii) 17 % = 0.17, 0.175, 2/11 = 0.18, 1/5 = 0.2 Correct

(iv) 2/11 = 0.18, 1/5 = 0.2, 17% = 0.17, 0.175 (×)

Hence only option (iii) is in order from smallest to largest.
