Expected value of the game = -5/6 dollars.
Step-by-step explanation
Given:
Even number = lose $5
1 or 3 = win $1
5 = win $8
Let's first form the table.
TABLE
Outcome: 1 2 3 4 5 6
Money: +$1 -$5 +$1 -$5 +$8 -$5
Probability for each outcome = 1/6
Expected value of the game = 1/6 ( $1 - $5 + $1 - $5 +$ 8 - $5)
= -5/6 dollars.
