You can use this method to work out lottery odds:
/**
* N is the population size OR total balls in the lottery draw
* K is the number of success states in the population OR the number of correct balls drawn from the pool
* n is the number of draws OR the number of times we draw from the pool to get the winning numbers.
*/
$N = 49; //Total balls in the pool
$K = 1; //Successful matches to win
$method = new Hypergeometric($N, $K, $K);
$odds = $method->pmf($K);
return 1/$odds;
//Will return 49
