It asks the following question: if each box of a given product (e.g., breakfast cereals) contains a coupon, and there are n different types of coupons, what is the probability that more ...
Different policy banks would offer different rates, though a payoff of 600 to 1 was typical. Since the odds of winning were 1000:1, the expected profit for racketeers was enormous. [41] The first modern government-run US lottery was established in Puerto Rico in 1934, [42] followed by New Hampshire in 1964.
E.g., if betting $10 on a 2-to-1 odds bet (upon win you are returned $30, winning you $20), then = $ / $ =. The figure plots the amount gained with a win on the x-axis against the fraction of portfolio to bet on the y-axis. This figure assumes p=0.5 (that the probability of both a win and a loss is 50%).

In a typical 6/49 game, each player chooses six distinct numbers from a range of 1–49. 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 ...
The expected utility hypothesis is a foundational assumption in mathematical economics concerning decision making under risk. It postulates that rational agents maximize utility, meaning the subjective desirability of their actions. Rational choice theory, a cornerstone of microeconomics, builds this postulate to model aggregate social behaviour.
There are 13 possible payouts ranging from 1:1 to 2,400:1. The 1:1 payout comes every 8 plays. The 5:1 payout comes every 33 plays, whereas the 2:1 payout comes every 600 plays. Most players assume the likelihood increases proportionate to the payout. The one mid-size payout that is designed to give the player a thrill is the 80:1 payout.
