## Need Help with Odds.?

heres the question

On the roulette table there are 36 numbers. You place a bet on 21 numbers leaving 15 free. What are the odds for a win. Expressed as both decimal odds and as a percentage.

Maths has never been my strong point i would really apreciate any help thanks.

### admin answers:

There are a total of 21 chances to win out of 36 possibilities, that means the odds of winning are 21/36.

Now to cancel it down you need to find common factors:

21 is 3*7

36 is 6*6 which is 3*2*3*2 so we can divide top and bottom by 3. So that’s 7/12.

Simplifying first makes it easier to do the division. If you use a calculator just bung in 21/36 you don’t need to simplify but I’m assuming you want to do it without a calculator.

How many times does 12 go into 7? Answer none so we have 0.

So how many times does 12 go into 70? The answer is 5, because 5*12 is 60, that leaves 10 so the answer so far is 0.5

Now bring down another zero making the 10 into 100. How many times does 12 go into 100? The answer is 8 because 8*12 is 96 leaving 4. So our answer so far is 0.58 and when we bring down the 0 we need to divide 40 by 12, which of course is 3 because 3 * 12 is 36 leaving 4. So we get 0.583 Wait didn’t we get 4 last time? That means we’re going to have a recurring decimal.

So our final answer looks like this.

…….0.58333333

…..______________

12|7.0000

…..70

…..60

———

….100

…..96

———

…….40

…….36

———

………4

…….4

So the decimal answer to your question is 0.5833333…

To express this as a percentage, multiply by 100 and stick a % sign on. To multiply by 100 just move the decimal point two places to the right.

So that is 58.33333%

Hope this helps.

## How to evaluate sin/cos/tan without a calculator?

I get some of it, but the other part I’m so confused about, please help me!

For example, I know that for sin (pi/3), you can convert it to degrees so that it would be sin (60), but the answer is sqrt3/2 and I don’t know how to get to that part! Please explain it to me!

Also, is the method different for cos, tan, csc, sec, and cot?

Please evaluate these step by step so I can see how to get the answer! Thanks so much!

1. tan (pi/4)

2. cot (pi/6)

3. sec (pi/3)

4. cos (pi/4)

5. csc (pi/3)

Thanks again!

SOHCAHTOA is the answer! 🙂

Sine=Opposite / Hypotenuse

Cosine=Adjacent / Hypotenuse

Tangent=Opposite / Adjacent

Opposite, Adjacent, and Hypotenuse are in reference to the angle in question…

Now this is extremely shorthanded and extremely misleading, but essentially correct. Sine, cosine, and tangent are nicknames for the ratios of sides of a triangle. We say the sine of an angle, never just sine. Anyhow, in the olden days before our parents were born, these ratios were found by physically measuring a triangle and the lengths of sides and doing the number-crunching by hand in the sand… This is why exact answers or short decimals were memorized, for ease of computation. So that is how you can find the sine of an angle, or any other trigonometric ratio without a calculator!

If you recall, Cosecant=1/Sine, Secant=1/Cosine, and Cotangent=1/Tangent. So Cosecant=Hypotenuse / Opposite, and so on.

Further, since these ratios are constant, we refer to them with the angle since it simplifies things.

1. Tan(pi/4)

pi/4 radians = 45 degrees

Visualize a right triangle with a 45 degree angle and a 90 degree angle. (You draw the reference triangle in the first quadrant.) That means the other side is 45 degrees. (All sides add up to 180 degrees.) This is a special type of triangle, since the sides have the ratio: (s for side)s=Opposite, s=Adjacent, and s*sqrt(2)=Hypotenuse, for all lengths of sides! No need to measure lengths or angles with this knowledge, or use a calculator, since s/s= 1!

2. Cot(pi/6)

pi/6 radians = 30 degrees

Again, we draw the reference triangle in the first quadrant. And surprise, we have a special case again, which is nice! In the 30 degree, 60 degree, 90 degree right triangle, the sides are in the ratio: s=Opposite (of 30 degrees), s*sqrt(3)=Adjacent (to 30 degrees), and 2s=Hypotenuse. Tanget= Opposite / Adjacent, BUT, Cotangent= Adjacent / Opposite. So s*sqrt(3) / s = sqrt(3) approx. 1.732

Using these explanations (if they are correct–I’m fairly sure they are correct) you should be able to get the rest! 🙂

But suppose we had:

sec(pi/7)

pi/7 radians = (pi/7)(180 degrees /pi) = 180/7 degrees, about 25.7 degrees. So looking over your special cases of the cosine of an angle, we know our answer must be in between the reciprocals of: the cosine of 0 and the cosine of 30 (degrees). The cosine of zero is 1, so the secant of 0 is also 1, and the cosine of 30 is sqrt(3)/2, so the secant of 30 is 2/sqrt(3), approx. 1.154. So how do we do this? Draw your triangle with the reference angle 180/7 or 25.7 degrees in the first quadrant. Since Secant=Hypotenuse / Adjacent, we need only compute these two sides of the triangle with the Law of Cosines, a.k.a. The Pythagorean Theorem for Right triangles! Make sure to have drawn your reference triangle very precisely! Set your adjacent side equal to some nice number, perhaps 3 inches, so that division is easier. Measure your hypotenuse carefully! If you have drawn correctly, the ratio of the Hypotenuse / Adjacent of a 180/7 degree angle or the secant of pi/7 radians should come out to be 1.111. It probably will be greater than or less than this since that is the calculator answer. 🙂 Note that this is between 0 and 1.154, as it should be! So with odd angles, without a calculator, it comes down the precision in drawing and measuring.

I hope this has been helpful!

Sharon asks…

## Bra size calculators….?

Anyone else found these really inaccurate? My measurements are 27″ and 30″ and I wear a 32AA or A but one **calculator** said I was 32B and one said I was 30A and I know a B cup would be waaayy too big because I just about fit into an A and I know 30 is way too tight.

Why do they say different things?

I’m 15 by the way please don’t take the mick out of small boobs I can’t help it 🙁

### admin answers:

27 means you should fit a 28 or 30, on the loosest hooks. Try them on, never assume they’re too small just because they’re unusual band sizes. I measure 26in on my torso and fit a 28, most 30’s are too big for me.

The most accurate size based on your measurements would be a 28B.

If you do find the 28 to be too small, a 30A would also be equivalent. In the unlikely even that size is also too small around, a 32AA is your next option.

Since it sounds like you’re between a AA and an A, you could also try a 30B or 28C (equivalent to the 32A). They may be slightly big however.

Cup size represents every inch of difference from the band to the bust.

In a 28 you’d be a B. 30-28 = 2in

A 30 would be an A, and a 32 would be AA.

These are actually all the same cup size on different torso sizes. What makes less than an inch of difference on an average size torso (32AA) would make more difference, 2in, on a slim torso (28B)

The smaller the number gets, the smaller the cup gets- a 28A is much smaller than a 34A.

Those calculations, outside of the 32B which is way off, are all accurate in terms of the cup. They say different things because of the number of inaccurate measuring methods still used today.

The most accurate way you can measure is this:

Torso + 1in (if odd) or +0in/2in (if even) = band size [27 + 1 =28]

Full bust size – band size = cup size [30 – 28 = 2]

## How can i beat the keno odds?

i want to win big in a casino

### admin answers:

I’m going to assume you mean online so I can try to give you a valuable answer.

Contrary to popular belief Keno can have as good of odds as just about anything else… How about 97%? That would be 13 numbers at 32red or 3dice.com

Below is an odds calculator you can use for non-fractional returns i.e. It doesn’t work on 3dice as they have .5 paybacks

Here is a java based calculator that will give you fractional returns http://www.pharosgaming.com/kl/KenolyzerAnalysis.html

If you are going to play in a ‚real casino‘ get the keno schedule from them via email, or stop in. This calculator will give you the variance, hit percentage, and jackpot frequency as well.

The only way you are going to ‚beat the odds‘ is to get lucky early and quit while you are ahead, and that is a guarntee 🙂
