In what sense “more than”?

If an odds give you more returs when you win, we say the odds are longer; otherwise they are shorter. The longer the odds on a horse, the less probability it has of winning.

Try not to use the terms “greater/more than” or “less than”. They are confusing.

The website says 'the bet must be placed on odds of 1/2 or more'. I think maybe they have just worded it badly. I assume they're saying the bet must be placed on odds of 1/2 or shorter as 7/5 would be longer and they say i can't use these odds for the bet.

I think what i need to do is find a 1/2 or shorter bet and confirm with the website this is acceptable. If it isn't then one of the people who have replied to me must be wrong.

Yes 7/5 has a lesser chance of winning but a greater return if it wins compared to 1/2.

So would you agree with the following statement: 7/5 is more than 1/2

The betting website doesn't.

#3 Re: Help Me ! » odds question » 2013-04-25 00:32:45

And 7/5 is definitely greater than 1/2 (it’s “greater” than 1/1 whereas 1/2 is “less” than 1/1).

This is where my confusion is because the website (think it's Ladbrokes) said 7/5 isn't more than 1/2. That's why i was asking here because i assumed it would be. I think i'm going to have to send them another e-mail to get them to clarify this.

#4 Re: Help Me ! » odds question » 2013-04-25 00:14:32

Ah okay i think that's the case because i asked the website by e-mail if 7/5 (this is what i wanted to bet on) would be more than 1/2 and they said it wouldn't. I was confused because i thought the 'more' was referring to the return. So 'more' than 50% profit return. I think you're right that they mean i have to bet on a favourite at 1/2 or 'more' which means an even greater favourite like 1/10 for example.

Thanks for the help. Sorry for the confusion.

That's just the way they write it on betting sites. I can't access betting sites at the moment as i'm at work but here's a copy/paste from a google search:

oddsconverter.co.uk/CachedGuide to UK, American and European odds formats and betting calculators. ... 1/2 , 1.50, -200, 13/8, 2.63, +162.50, 9/2, 5.50, +450. 8/15, 1.53, -187.50, 17/10 ...

At oddsconverter it shows 1/2 as a decimal bet of 1.50. This means if i bet £10 i get £15 return. So the person i'm betting on would be considered a favourite to win.

#6 Re: Help Me ! » odds question » 2013-04-24 22:54:35

If player 2 is 2:1 against, that means 1 is a 2 to 1 favorite. I bet 10 dollars on 1, I expect to get 5+10 dollars back.

Yes that's what i said in my last post. See:

So if the odds were 1/2 and i placed a £10 bet i'd get a return of £15 if player 1 won.

That's not answering my question though. sad

I think we're getting crossed wires here. I understand what you're saying but i think because of the way i've written the betting odds you don't understand what i'm saying. I'm not 100% sure how bookies write betting odds on their website so i could be writing it incorrectly. I thought it is written as 1/2 but could be wrong and maybe it's 1:2 or something like that.

As an example of betting odds if i bet on player 1 to beat player 2 and the odds were 1/10 and i place £10 on the bet and player 1 wins i would be given a return of £11 (original bet plus £1). So i wouldn't be getting a good return because player 1 is expected to win most of the time. So if the odds were 1/2 and i placed a £10 bet i'd get a return of £15 if player 1 won.

Basically i have won a free bet at a bookies and it says it has to be placed on odds of 1/2 or more. I don't understand what is more than 1/2. I assumed it means if my profit return is greater than 50% as it would be at 1/2.

#8 Re: Help Me ! » odds question » 2013-04-24 21:25:37

Okay i thought they wrote it as 1/2 on the site but could be wrong. Either way it should be written as 1:2 then.

So if i bet £1 at 1:2 i would get a £1.50 return if the bet won. The original bet plus 50%. I don't understand what they mean by odds greater than 1:2.

Hello and thanks for the help

Let me rephrase the original question. So ignore what i said before. If a bookies says i can place a bet at 1/2 odds or more what do they mean by this? What is considered more than 1/2?

what odds are more than 1/2?

For example is 2/3 more? What about 7/5?

Hi

I'm after some info on how to work out probability using poker hands.

I've been told that if i hold two different cards in my hand the chance of one of them coming down in the next five cards is about a 55% chance. Worked out by doing this:

44/50     0.8
43/49     0.87
42/48     0.87
41/47     0.87
40/46     0.87

x these numbers by each other and get 0.45 (roughly).

1 - 0.45 = 0.55

What i wanted to know now is if i hold two suited cards in my hand like two spades what is the chance of 3 spades coming down in the next 5 cards and how do i work this out?
