Question

Remember that the spins of the wheel ore independent and that Appendix B has the Probability Reference Sheet with Roulette bet explanations. Suppose you are going to spin a European Roulette wheel twice in a row. Find the following, showing work and 4 decimal places. You place a "3^rd Dozen" bet on the first spin and then decide a "30/32 Corner" bet on the second spin. What is the probability that you win on both spins? You place a "Straight Up 5" bet for both spins. What is the probability that you win on both spins? You decide to bet "3^rd Dozen" for both spins. What is the probability that you lose on both spins? You decide to bet "13 Street" for both spins. What is the probability that you win on at least one spins?

Explanation / Answer

(A)

There are total 37 numbers available on the wheel.

Getting a number from 3rd dozen in first spin, probability = 12/37

Getting a number from 30/32 corner in second spin, probability = 4/37

hence required probability = 12/37 * 4/37 = 0.0351

(C)

Not getting a number from 3rd dozen in first spin, probability = 25/37

Not getting a number from 3rd dozen in second spin, probability = 25/37

Hence required probability = 25/37 * 25/37 = 0.4565
