Why do people fool themselves when they gamble ? I hear many people many times say you should roll lots of 98% or 90% or whatever odds on dice.
That's a bad idea and way less profitable so why do people fool themselves into thinking its better to bet low odds.
Of you roll 50% or 5 rolls at 90% some people will tell you to do the 90% one. The chance is the same actually. You actually lose half your profit rolling at 90%
5rolls of 90% = 50% profit.
1 roll at 50% = 100% profit.
Ita basic maths people....
I think you're wrong. 1 roll at 50% can make you lose 100%. Whereas 5 rolls on 90% can lead to win with a higher probability
This is wrong! 10% x5 = 50% and is 50% more than on 100% and what if you lose first time on 90% you risk all fpr 10% ? Rather risk all fpr double.
Wow... the level of maths fail here is astronomical...
It is quite obvious reading the numerous responses on this thread that there is a basic lack of understanding of how probability and statistics work.
Firstly, 5 rolls at 90% IS NOT equal to the chance of 1 roll at 50%... the 10% chances of lose DO NOT stack up each roll... this is also not a conditional probability... each roll is independent of the previous roll(s)... (assuming the game isn't rigged)
So... if you have 90% odds of winning...
roll 1: lose % = 10%
roll 2: lose % = 10%
roll 3: lose % = 10%
roll 4: lose % = 10%
roll 5: lose % = ?? I'll award 100internetz to the first person that can guess the answer
....
roll N: lose % = 10%
likewise... if you have 50% odds of winning...
roll 1: lose % = 50%
roll 2: lose % = 50%
roll 3: lose % = 50%
....
roll N: lose % = 50%
90% chance of winning is obviously greater than 50% of winning.... to put it another way... if you roll 10 times, at 90% you should win 9 out of those 10. At 50% you should win 5 out of those 10. The casinos recognise this, and therefore adjust the payouts accordingly, so you win more often, but you win less each time.
Going by the logic you guys are using, you should NEVER EVER play 50% more than once... because 2x 50% = 100% so you are guaranteed to lose right???
That obviously explains why you can get those 5+ win streaks on 50% odds... oh... wait...
Secondly, to the guy going on about running into house edge "more often" taking 5 rolls... *sigh*... the house edge is built into the odds and payouts you are getting... this is why the dice site doesn't even offer 50% @ 2x payout... If you want 50%, the payout will be 1.975x-1.99x... If you want 2x they only offer 47.5-49% of winning... That is their "mathematical" edge... they don't give you "true" payouts for the odds you get...
Honestly, I need to find some investors and start an online gambling site... no wonder they make so much money... with so many people gambling money who clearly don't understand how it works.
