Cameron is betting on a game in which the probability of winning is $1$ in $4$. He's lost ten games in a row, so he decides to double his bet on the eleventh game. This strategy shows a. good logic, because he's due for a win. b. good logic, because he's more likely to win when the bet is larger. c. poor logic, as he has a $75 \%$ chance of losing the double bet.
