As a new lottery player, I'd like to calculate the odds of winning. Each NYLottery game has posted

odds, however, my calculations give different odds. Perhaps I am not doing it right, or

they use a different method, but here are my results compared to theirs:

If we use #'s 0-9, and pick one number, then odds of winning are 1 in 10. Thus, I just have to

buy 10 tickets, play all numbers, and will get a winner 100%.

If 3 numbers are picked, then it's 10x10x10, or 000-999, thus 1:1000 correct?

But, in a single Take5 game, numbers cannot repeat. Key space is 39.

thus 39x38x37x36x35 = 69,090,840

To win top prize(all 5 #'s matched), their odds are 1:575,757.

How is that calculated?

Pick10 has better odds, eventhough the key space is 80. Since 20 numbers are picked(1/4),

and you pick 10(1/8), top prize matches 10, thus you have 2x chances to win. But, that's the same odds as matching 5 to 10 if key space was 40.

Winning Numbers Matched Per Game: 10

Prize: $500,000

Chances of Winning

on one Game Panel

1:8,911,711

Isnt it 80^10?

In any case, how is that any better than playing slots in Vegas or A.C.? 1c, 5c, 25c, gives more games than $1 on above. I played 1c at a casino in Vegas, and won $10; that's 1000%.

How To Calculate Odds

The reasoning behind this is, when one picks 5 numbers out of a pool, there are 120 different ways in which those 5 numbers can be picked, ranging from 1-2-3-4-5 to 5-4-3-2-1, hence the game odds are calculated as (39x38x37x36x35)/(1x2x3x4x5). That formula yields 575,757.

Pick 10 is far more complicated, since 10 different games are being played from one draw.

where you quote 39x38x37

that is correct if you want to get the exact order of drawn numbers, ie 1st ball drawn is a 5, it is indeed 1 in 39, but if the order isnt important then there are 5/39 odds for 1st ball. and then 4/38 for second ball. 3 of 37 balls. etc.

math is something like, 39x38x37x36x35 / 5x4x3x2x1
