LOTTERY DRAW "PROFIT-LOTO"

When you play at Profit casino, Lottery are credited



Every Sunday at 23:00 (MSK) the lottery "PROFIT-LOTO" is drawn. The total prize fund is not limited. The participant's goal is to guess three numbers out of 37 possible. The number of accumulated tickets is reflected in the Lottery field of the player's profile. Unfilled lottery tickets are not tied to a specific draw date. Filling is done using the built-in interface in the lobby of the "PROFIT-LOTO" draw. Filled tickets automatically participate in the next draw. To determine the winning numbers, three spins are made on the roulette. The order in which the numbers fall out does not matter. The presence of participants on the site at the time of the draw is not required. The verification code for checking the fairness will be available 2 hours before the start of the draw.
The reward for correctly guessing two numbers is $50. For three correctly guessed numbers, $1000. The winnings are automatically credited to the winners' accounts after the lottery ends.
Accumulated lotteries can always be sold at the offered price in the draw lobby.
Information about the drawing will be available for a week.



I'll try this lottery, although selling tickets for $0.50 is also possible.

Don't guess any of the 3 guessed numbers in 1 spin
Loss1 = 1-3/37 = 0.91891

All three times, not guessing a single number
Loss3 = 0.91891^3 = 0.7759 = 77.59%

How to calculate the probability of guessing 2 numbers (out of 3) in 3 roulette spins?

Guess 1st spin 3/37
Guess on the 2nd spin 2/37 (2 numbers left guessed)
Guess on the 3rd spin 1/37 (1 guessed number left)

You need to do this three times in a row, so
P = 3/37 * 2/37 * 1/37 = 0.000118453 i.e. 0.0118%

How to calculate the probability of guessing 2 numbers (out of 3) in 3 roulette spins?

The player wrote down 3 numbers and the casino makes 3 spins.
Spin outcomes how to guess exactly 2 numbers:

- (3)
+ (3)
+ (2)
P = 3/37 * 2/37 = 0.004382 = 0.438%

+ (3)
- (2)
+ (2)
P = 3/37 * 2/37= 0.004382 = 0.438%

If the numbers were not repeated, it would be like the combinatorics of the combination "5 out of 36"

To calculate the probability of winning, we will need not probability theory, but rather combinatorics.
So, a little math.
A combination is a selection of k elements from n given data without regard to order (e.g. selecting all at once or even sequentially if the order is deemed unimportant as a result of the selection).
The number of combinations is calculated using the formula:
Factorial ( n! ) is a number that is equal to n*(n-1)*(n-2)*(n-3)..*1
For example, 5!=5*4*3*2*1=120.

That is, the total number of all possible combinations is calculated using the formula:
(x) numbers from (n) = (n * (n - 1) * (n - 2) * (n - 3) … * [n - (x -1)] ) / x!

For example, for the Gosloto 5 out of 36 lottery, the total number of combinations is calculated as follows:
5 out of 36 = 36 * 35 * 34 * 33 * 32 / 1 * 2 * 3 * 4 * 5 = 376,992.
Thus, the chance of winning for Gosloto, or any other lottery in which you need to guess 5 numbers out of 36, is 1 in 376'992.
