Question 87157
You can look up the # of tickets sold using the internet.
Assume a person buys one ticket
Probability he wins = 1/# of tickets sold
Probability he loses = 1-(1/# of tickets sold)
Odds in favor of his winning = [Prob(he wins)/[Prob(he loses)] = a/b
If the result is a/b you can express the odds in favor of his winning as a:b
