You decide to bet on ten spins of the roulette wheel in European roulette and to use the double-up strategy. Under this strategy, you bet on red each time and you double your bet if red does not come up. If red comes up, you go back to your initial bet of 1 euro. Use computer simulation to find the expected value of your loss after a round of ten bets and to find the expected value of the total amount bet during a round. Can you explain why the ratio of these two expected values is equal to 1 37?
