Answer:

$0

Step-by-step explanation:

So there's a 0.1 probability of winning $130000 minus $13000 cost and 0.9 chance of losing $13000

Then the expected value of this game is

Probability of winning * winning value + probability of losing * losing value

0.1*(130000 - 13000) - 0.9*13000 = 11700 - 11700 = $0

Anyone playing this game should make even after a while
