Answer 1

Answer: if 1 represents the game at the top and 7 the game at the bottom, the order is 1, 6, 5, 2, 3, 7, 4

Step-by-step explanation:

in a game where the expected value is zero, if your probability to win is p and the entry cost is C, then you should win an amount W =  C/p

then p = C/W

1) C = $5, W = $200

p = 5/200 = 0.025

2) C = $6, W = $300

p = 6/300 = 0.02

3) C = $9, W = $468

p = 9/468 = 0.019

4) C = $8, W = $440

´p = 8/440 = 0.0181

5) C = $7, W = $315

p = 7/315 = 0.0022

6) C = $4, W = $168

p= 4/168 = 0.024

7) C = $10, W = $540

p = 10/540 = 0.0185

Then the order, from least probability to greatest probability of winning is:

1, 6, 5, 2, 3, 7, 4
