將在星期三開獎的美國「強力球」（Powerball）頭彩，獎金預計已上看13億美元！這是有史以來，全世界最大的頭彩。
中獎號碼是由69個白球中，抽出5個，並從26個紅球中，抽出1個而組成的。
六個數字全中的機率，是2億9千2百2十萬分之一。這跟拋硬幣，得到連續28次人頭的機率差不多。
專家表示，讓電腦隨機選號，比自己選號的勝算大。因為一般人選號時，常會用出生日期，號碼一般低於31號，但電腦選的1至69號都會有。
買越多彩券，中獎機會當然越大。但是，每張彩券2美元，要買下所有可能的數字組合，可得耗資5億8千4百萬美金。
所有獲獎者都須繳納聯邦所得稅，一般美國市民要付25%，但實際獎金，要看所在的州而定。
阿拉斯加、佛羅里達、內華達、南達科他、德州、華盛頓州和懷俄明州並不徵收得獎稅。但紐約市的獲獎者，則需支付8.8%的稅金給州政府，及3.9%給市政府。
你也玩「強力球」嗎？要不要試試手氣啊？
英文原文：
The grand prize of the US Powerball to be drawn on Wednesday has increased to an estimated $1.3 billion.
That’s the largest jackpot in the world guys
Powerball picks 5 out of 69 white balls and 1 out of 26 red balls which together make the winning numbers.
The odds to match all six numbers are one in 292.2 million, similar to the odds of flipping a coin and getting heads 28 times in a row.
Allowing the computer to pick your numbers will increase the chances of winning as people generally use birthdates which normally fall below number 31 whereas the computer chooses anything between 1 and 69.
The odds of winning increase if multiple tickets are bought. However, buying all possible number combinations at US$2 each would cost US$584 million.
The payout depends on where players live, but all winners must pay federal income taxes. This is around 25 percent for US citizens.
The states of Alaska, Florida, Nevada, South Dakota, Texas, Washington and Wyoming do not tax winnings. Winners in New York City have to pay both 8.8 percent state tax and 3.9 percent city tax.
