Another example is when people commonly confuse the odds with winning the lottery. People think that by buying MORE tickets, they'll increase their odds of winning. If you have a 1:1,000,000,000 chance of winning, buying 100 tickets gives you the same odds of winning as buying 1 ticket. No matter what, the odds of winning always stay at 1,000,000,000. So, buying 1 ticket gives you 1:1,000,000,000 chance of winning, buying 100 tickets gives you 100:1,000,000,000 chance of winning.
