Talk:Lottery mathematics

From Wikipedia, the free encyclopedia

I have added a section of calculating a score of n when selecting 6 from 49. Anyone know why the table of contents isn't showing, please?--New Thought 17:04, 3 March 2006 (UTC)

hmmmm... when it got to 4 sections, it seems to have added it automatically.

I believe the table under "Odds of getting other possibilities in choosing 6 from 49" is incorrect. The fractions listed are inverted. The {49\choose 6} should be in the denominator for each of those cases. The other numbers in the table are correct.

Whoever made the comment above was correct. I have made corrections to the table and the explanatory text. --Aaron Lehmann 11:47, 18 December 2006 (UTC)

Good morning, I have only a basic college level course in statistics and probability, so it is not the equations in the article I am commenting on because the math is correct even if I think there is an easier way to explain it all, it is the explanation paragraph I think is not really correctly worded:

"Starting with a bag of 49 differently-numbered lottery balls, there is clearly a 1 in 49 chance of predicting the number of the 1st ball out of the bag. Accordingly, there are 49 different ways of choosing that first number. When the draw comes to the second number, there are now only 48 balls left in the bag (because the balls already drawn are not returned to the bag), so there is now a 1 in 48 chance of predicting this number."

My suggestion is that if the numbers do not have to be picked in order, there is not "clearly a 1 in 49 chance" of predicting the first number, but actually a 6 in 49 chance of picking the first ball correctly There is a 5 in 48 chance of picking the second correctly and so on. Only in the case of the balls being required to be picked in order would each selection have a 1 in something chance. 49/6 x 48/5 x 47/4 x 46/3 x 45/2 x 44/1 wspruce@msn.com

The 49/6 x 48/5 x 47/4 x 46/3 x 45/2 x 44/1 Yields the number of combinations available (13,983,816). I am planning on adding a column in the table 1/Probability because that is what is on most play slips. —Preceding unsigned comment added by 198.190.9.225 (talk) 15:03, 9 June 2008 (UTC)

[edit] 0-99 no of lottry mathemetics

privious no (100-privi. no)+50 is that basic no then next no wich is coming suppose that 97 then privious no (-) ,(+) for ex.


    privi.no is 114 then next no is 97

         114
         x   y  z  a   b   c
         97 17 211 03 131 325
                   111 117 225
                   u   k    r

          b+.5(z-a)= ?
          b+.5c+.25(z-c)=?
