A Small Steel Roulette Ball Rolls Around The Inside

A small steel ball rolls counterclockwise around the inside of a 50 cm diameter roulette wheel. The ball completes exactly two revolutions in 1.5 s. A) what is the balls angular velocity? A Newton's Cradle is some times used to demonstrate the Law of Conservation of Momentum but, I noticed anomaly. Specifically, whenever the steel balls collide, I hear a clicking sound and that requires energy. This tells me some of the kinetic energy of a moving ball transforms into thermal and accoustic. The various roulette ball sizes are 3/8 inch, 7/16 inch, 1/2 inch, 5/8 inch and 3/4 inch. But almost every modern casino uses either 5/8 inch or 3/4 inch balls. And they are almost always teflon or ivorine as shown above. The ivorine ball is usually pale yellow, and the teflon is flat white. Although everyone wants to win at the roulette table, roulette balls are easy to lose, whether playing roulette at home or anywhere. Therefore, you should always have more in case any go missing. We have both ¼” steel replacement roulette balls and ¾” white plastic roulette balls, so be sure to grab some extras for back-up.

Roulette is one of the most entertaining, and accessible, games in a Las Vegas casino.

Even seasoned roulette players will be surprised by some of the fascinating aspects of the game we’ve hastily slapped together.

Let’s start with a couple of names for things we didn’t know had names. First, there’s a term for when a roulette dealer gathers and restacks chips, it’s called “mucking.”

Also, there’s another name for the object used to mark a winning number: A “marker” is also called a “dolly.”

Roulette markers, or dollys, come in all shapes and sizes.

It’s also worth noting a roulette dealer is also called a “croupier.”

Are we having fun yet?

Here’s a surprising fact about roulette: Just as people are left and right-handed, there are also right-handed and left-handed tables.

If you’ve played roulette, you’re probably more familiar with the right-handed table. The wheel sits to the right side of the dealer.

We’re going to pretend Hard Rock reserved this right-handed table for us. Just go with it.

Here’s a left-handed roulette table. If you guessed the wheel is to the left of the dealer, you’re well on your way to a job as an elected official.

The left-handed layout can cause confusion with players. Example: “It’s backwards! Pay me for the number I thought I was betting on!”

Here’s what happens when a right-handed roulette table and a left-handed roulette table hook up in Las Vegas.

Here’s a relatively useless fact: On roulette tables, the ball spins in the opposite direction of the wheel’s rotation.

On a right-handed table, the wheel goes counter-clockwise while the ball goes clockwise. On a left-handed table, the ball goes counter-clockwise while the wheel goes clockwise.

Interestingly, a roulette dealer trained in a European casino will reverse the rotation of the wheel and ball following every spin.

If you see a triple zero roulette table, just run.

Many of the procedures and devices on a roulette table are to try and ensure the results are random.

On a roulette wheel, for example, small devices called “canoes” are installed to give the ball additional obstacles to divert the ball from a predictable path as it falls into the wheel.

Canoes are also called frets, making this blog post, officially, the most useless in the history of the Interwebs.

Players sometimes try to pick up on a dealer’s pattern or rhythm, called a “dealer signature,” to predict where the ball is likely to fall. When player’s see a pattern, they practice something known as “section shooting,” or betting in certain areas of the wheel to try and gain an advantage over the house.

Now, let’s talk chips!

It’s a little-known fact that dealers, when pushing stacked chips to players, can’t move the chips in a way that conceals them from the security cameras above.

Dealers spend a lot of time practicing pushing stacks of chips. If you’re ever asked, 20 is the standard number of chips in a stack at a roulette table. Try pushing five stacks of 20 chips without them tipping over!

Unlike other casino chips, roulette chips have no value away from the table and can’t be traded for cash at the casino cashier, or “cage.”

That’s because roulette chips have no set value. Players determine what value a chip will have. Chips can be worth $1, $5 or more, as stated when the player buys in.

Taking chips from a roulette table is discouraged, because it’s a common scam to buy in for a low denomination (say, $1 per chip), to take chips away from the table, then return at another time, buying in for a higher denomination (say, $5), then slipping the previous low-value chips back into the game for an immediate profit. It happens quite often, actually, and the practice is illegal.

We’ve been playing roulette quite a long time, but only recently learned about “picture bets.”

Picture bets are a way for dealers to easily recognize and pay out common chip combinations. Those chip combinations often have colorful names, and dealers memorize the names and payouts to keep games moving. (The more spins, the more money a casino makes, by the way. The house edge for double zero roulette is 5.26%.)

Think of picture bets as flash cards for dealers.

Here are a couple of picture bets, and let’s say the chips are worth $1 just to keep it simple.

The “Mickey Mouse” is two corners (each pays 8-to-1) and one straight up number (pays 35-to-one), and it pays $51.

To see some of these “picture bets,” like the Mickey Mouse, you have to view the bets from the perspective of the dealer.

“Deck of Cards” is called that because it pays $52 (52 cards in a deck): It’s one straight up number and one split (pays 17-to-1).

A “Basket” pays $67 for two corners and three splits. We’ll turn it on its side for you.

We flipped it so you can see the basket. You’re welcome.

A “Picture Frame” is one straight up number, four corners and four splits. This pays a healthy $135. An “Empty Picture Frame” is the same configuration, but without the straight up number.

Our favorite picture bet, because it’s the dirtiest, of course, is “Dinner for Two.” This bet is two splits and a straight up number. It pays (wait for it) $69.

Because “dinner for two.” We’ll wait.

Hey, roulette dealers often have a lot of idle time on their hands!

Here’s something to watch the next time you’re near a roulette table: Notice that dealers in a live roulette game must keep the wheel in perpetual motion. It’s a gaming regulation.

Now, have fun, and give roulette a spin.

Algebra -> Probability-and-statistics-> SOLUTION: 2.2 Roulette Wheel. The game of roulette involves spinning a wheel with 38 slots: 18 red, 18 black, and 2 green. A ball is spun onto the wheel and will eventually land in a slot, w Log On


Question 1113469: 2.2 Roulette Wheel. The game of roulette involves spinning a wheel with 38 slots: 18 red, 18 black, and 2 green. A ball is spun onto the wheel and will eventually land in a slot, where each slot has an equal chance of capturing the ball.
(a) You watch a roulette wheel spin 3 consecutive times and the ball lands on a red slot each time. What is the probability that the ball will land on a red slot on the next spin?
(b) You watch a roulette wheel spin 300 consecutive times and the ball lands on a red slot each time. What is the probability that the ball will land on a red slot on the next spin?
(c) Are you equally confident of your answers to the parts (a) and (b)? Why or why not?

You can put this solution on YOUR website!

The wording of the problem indicates that it is a fair roulette wheel, so the probability of landing on a red spot on each spin is 16/38 = 8/19. That probability is the same, regardless of the outcomes on previous spins.
So the answers are
(a) 8/19
(b) 8/19
(c) Yes, as explained above
