Answer:

a) - $0.169

b) - $0.04242

Step-by-step explanation:

Data provided in the question:

Bet amount = $4

Probability of losing $4 = \frac{258}{495}

Probability of gaining $4 = \frac{237}{495}

a) The expected value

= Winning amount × winning probability - Losing amount × Losing probability

= $4 × \frac{237}{495} - $4 × \frac{258}{495}

= $4 × \frac{237-258}{495}

= - $0.169 (Negative sign means loss)

b) The amount lost for each dollar = \frac{\textup{Expected Value}}{\textup{Bet amount}}

= \frac{\textup{-0.169}}{\$\textup{4}}

= - $0.04242
