Question 1022342
Assuming a "fair game" has expected payoff zero, the expected number of dots is


*[tex \large \frac{1}{6} \times 1 + \frac{1}{6} \times 2 + \ldots + \frac{1}{6} \times 6]


which is equal to


*[tex \large \frac{1}{6}\left( 1+2+3+4+5+6 \right) = 3.5]


Then 3.5 * $0.50 = $1.75 should be charged.
