Poker Odds Calculator TournamentIndicator

It’s possible, but very unlikely, that someone got bored one day and scratched the number off. The odds, however, are that the calculator was stolen. There’s not much you can really do about it at this point. If you had noticed it before you purchased it, you could have turned it done. If you really feel you want out of it, talk to the police department. You didn’t knowingly buy a stolen article and you’re trying to make it good, so they have no reason to do anything to you. If it was reported, they can see of the serial numbers that remain are in their files. You could just toss it, $20 isn’t that big a deal. Or you could give it to Good Will or something like that. Other than that, use it and just learn from the experience.

There is a bet calculator available on my website

The number of ways you can draw 20 from 80 is 80C20. Now if we assume that n of the 20 numbers are yours then the other 20-n numbers are drawn randomly from 80-9 since they have to be drawn from the 71 numbers that are not yours. This leaves 71C(20-n) ways to draw the last 20-n numbers. The number of ways that you can have n of your 9 numbers are 9Cn. This reasoning provides the formula:

your odds = 9Cn*71C(20-n) to 80C20

Where n denotes an amount between 1 and 9 of how many numbers you got right.

17 in 23,471,690 to get all 9 which is approximately
1 in 1,380,688

153 in 4,694,338 to get 8 which is approximately
1 in 30,682

But you have the formula so just calculate 9Cn*71C(20-n) in 80C20 and let your calculator reduce the fraction between the two in order to get these relations.

It has to be said, that these numbers really show what the tendency is on THE LONG RUN. But there is another concept called the „mean waiting time“ which denotes the theoretic mean of the number of draws before you succeed.

This is a somewhat lower number than the numbers above because an instance of probability 1/n usually happens before n trials has been carried out.

To see this consider a dice. It will usually show six before six repetitions. So the mean waiting time for the occurence of a six is lower than 6 though the probability is 1/6.

Trust me you really need the calculator, and for SATs and college and every math course from now until you’re done with school for good. Dont worry about it! 😛
those calculators are so helpful. That’s odd that your school doesnt lend them to you, that’s what mine does. So now i have the dilemma of not having my own for college yet D:
you’re a lucky one! Haha

If you managed to type this into Y!A and have an account here, chances are very good that you have a scientific calculator. If you are running some flavor of MS Windows, In NT, 2000, and XT, you can get to it by going to Start -> All Programs -> Accessories -> Calculator. By default you get just a four-banger, but if you go into the View menu, you can select the scientific calculator instead. The procedure for getting to the calculator will be a bit different for MAC machines, but they have one also.

Meanwhile, except for the signs, this is just mental arithmetic.
Rules for signed addition/subtraction:

1. Convert subtracts to adds by changing the sign of the subtrahend (the number you are subtracting). Then use the rules for addition. Taking #20 as an example,
-4 − (-8) = -4 + (+8)
or you may prefer to think of it as
-4 + (-(-8)) and use rule 2 below to clear out the redundant negative signs.

2. For numbers with nested multiple negative signs in front of them, such as #14, the negative signs will obey the same rules as for multiplication and division: count the negative signs and negative signs cancel in pairs. If the number of negative signs is even, they all canceled and the result is positive. If the number is odd, there is one negative sign left after cancellation is complete and the result is negative.

Example: -(-7) = 7 because two is even and all the negative signs cancelled.
-(-(-(-(-7) = -7 because 5 is an odd number and like signs, so one is left over at the end.

3.
A. To add numbers of LIKE SIGN, add the absolute values (magnitudes) of the numbers to get the magnitude of the answer. The sign will be the same as the sign of the numbers.

B. To add numbers of OPPOSITE SIGN, subtract the magnitudes (absolute values) of the numbers to get the magnitude of the answer. The sign will be the same as that for the number with the larger magnitude. If both numbers have the same magnitude, as in questions 5 and 6, the answer will be zero, which has no sign.

Using example #20 again:
(-4) + (+8) (or, if you prefer, -4 + 8)
Unlike signs, so subtract the magnitudes 8 and 4 to get 4. The number with the larger magnitude is 8, which is positive, so the answer is +4. In signed arithmetic, numbers are typically assumed to be positive unless otherwise specified, so you may drop the redundant + sign, as is conventionally done.

Now do the others, preferably without a calculator. You really need to master signed because it will continue to haunt you in your math and science courses until you do.
