##### Probabillity Question
« on: February 12, 2017, 03:31:45 PM »
Hello everyone,

Can someone tell me the probabillity in percentage of the following happening with
succes? I will be all winnings so it's a paroli variant.

10 numbers and when won
15 numbers and when won
20 numbers and when won
25 numbers and when won
30 numbers and quite

Can you tell me how large the probabillity is to make it all the way?

Thanks for everything!

Just multiply the individual probabilities:

10/37 * 15/37 * 20/37 * 25/37 * 30/37

(continuing Bayes' post)

= 0,032 or 3,2%

Just for reference, a single number has 2,7% and a split has 5,4% percentage of a hit.

10 = 48 <=== MAX EXPECTED SPINS FOR THE WIN
15 = 30 <===
20 = 20 <===
25 = 14 <===
30 = 9 <===

Without some kind of advantage, the worst spins will crush any direct progression.  So it is necessary to create a "betting scheme" to make the worst expected results "accessible".

LOL MOD PARTY!

Long shots lose most of the time, but if they are cheap, and we are lucky, we could sometimes go for it.

Parlay a straight up start with a dollar, do it not too often, just like a lottery, but better winning odds .
