The chance of winning can be demonstrated as follows : The first number drawn has a 1 in 49 chance of matching.

Well, if the probability of throwing a five on one dice.6 per cent, you might assume that its twice as likely (33.3 per cent) to happen when doubling the number of dice.

In a future article, well take a look at working out the probabilities on dependent events, which may even include the chances of that elusive number 13 lottery ball coming out next onto the rack!However; the order of the 6 numbers is not significant.Again, there is only one type of event in which both dice show the same particular number, so 1/36.The odds are usually presented as a ratio.This yields a final hp laser printer rebate formula of ( n k ) ( 49 6 ) displaystyle n choose k49 choose 649 over 6*48 over 5*47 over 4*46 over 3*45 over 2*44 over.The generalisation of this formula is called the hypergeometric distribution.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.

The range of possible combinations for a given lottery can be referred to as the "number space".

You might object that such an event would be most unlikely - and youd be right.

This back to front method becomes more useful as the number of dice increase.

For example, if the odds for a football team losing are 1 to 5, it means that there are 5 changes of them winning and only 1 of them losing.Again, the number of possible outcomes is the number of those for each dice, raised to the power of the number of dice in play.The total number of combinations giving that result is, as stated above, the first number multiplied by the second.You're absolutely right, and we have corrected the article to say "at least one of the two dice." The probability of a 5 coming up on only one of the two dice is 10/36 because we don't include the permutation where the first and second.Note that in calculating probabilities it is necessary to keep each outcome separate, even when they seem to be the same.
