The casino has an interesting new game.
You start with a bankroll of $100 and place a $1 bet on a number 1 through 6. You then roll three dice, and if any of the dice rolls match your original bet, you win the number of matching dice ($1, $2, or $3) plus your original $1 bet back. If you lose, your bankroll goes down $1. You must play the game 100 times and keep the sum of your bankroll at the end of the 100 dice rolls.
What are the odds of winning?
Taking the bet is a personal choice, but the odds are not in the bettor’s favor, as you have more to lose than possibly gain.
On average, you will lose $8, but you could lose up to $50 or possibly gain $36.
The average is 92.2649 The percentage over 100 is 0.2243 The min result is 50 The max result is 135
