If the six numbers on a ticket match the numbers drawn by the lottery, the ticket holder is a jackpot winner—regardless of the order of the numbers. The probability of this happening is 1 in 13,983,816. The chance of winning can be demonstrated as follows: The first number drawn has a 1 in 49
Lottery competition Lottery competition Lottery competition in ecology is a model for how organisms compete. It was first used to describe competition in coral reef fish. Under lottery competition, many offspring compete for a large number of sites (e.g., many fry competing for a few territories, or many seedlings competing for a few treefall gaps). Under lottery competition, one individual is chosen randomly to "win" that site (typically becoming an adult soon after), and the "losers" typically die off. Thus, in an analogy to a lottery or raffle, every individual has an equal chance of winning (like every ticket has an equal
