“Rafa Nadal and I have an average of 5 French Open titles.” That is a quote I'm going to have to remember. Should come in handy often.

"Bill Gates walks into a bar and the average net worth of everyone there goes up $1M"
- knodi123 9y ago
  Bill's net worth is $90 billion. It would be more accurate to estimate that everyone's average net worth of the bar population goes up by several billion.

  More like "Bill Gates walks into a football stadium and the average net worth of everyone there goes up $1M"
  - eesmith 9y ago
    Assuming a stadium with 30,000 seated people, that would imply an average net worth of about $67. With 10,000 seated people, $200.
    - cjlars 9y ago
      Your math's off, $90BN / 30k = ~$3M: https://www.google.com/search?q=90.2+billion+%2F+30000&oq=90+&aqs=chrome.2.69i57j0j35i39j0l3.3564j0j7&sourceid=chrome&ie=UTF-8 https://www.google.com/search?q=90.2+billion+%2F+30000&oq=90...

  Yeah, but that's only because the bar has 90,000 people in it. If the bar had more people in it, the net worth wouldn't go up as much.
- eesmith 9y ago
  How big is this bar? Time bring out the quadratic equation. If the average net worth of a US citizen is $100,000 (it's less, but I'll go with that), and Gates has a net worth of $90 billion, and the average net worth of those people goes up $1M: average worth = aw = 100000 n people total worth = aw * n Bill Gates comes in: total worth' = aw * n + 90000000000 aw' = (aw * n + 90000000000)/(n+1) difference = aw' - aw = (aw * n + 90000000000)/(n+1) - aw * n = 1000000 = (100000 * n + 90000000000)/(n+1) - (100000 * n) = 1000000 => n ≈ 944 people in the bar https://www.thebalance.com/american-net-worth-by-state-metropolitan-4135839 https://www.thebalance.com/american-net-worth-by-state-metro... says the average net worth is $68,828 in 2011, which implies about 1,136 people in the bar. Big bar. If they were millionaires already, then only 300 people are needed. If they were billionaires, only about 30.

    > difference = aw' - aw > = (aw * n + 90000000000)/(n+1) - aw * n = 1000000 Somehow aw turned into aw * n there, which sent your calculations wildly off. You want: n * aw + 90 * 10^9 = (n + 1) * (aw + 10^6) n * aw + 90 * 10^9 = n * aw + n * 10^6 + aw + 10^6 90 * 10^9 - (10^6 + aw) = n * 10^6 n = 89999 - aw / 10^6 i.e., almost 90000 people, no matter how wealthy the population of the bar is.

      > no matter how wealthy the population of the bar is. That doesn't sound right. What if the population of the bar is as wealthy as Gates? The average net worth should change if you add another value equals to all the previous ones. Am I reading something wrong?
      - cperciva 9y ago
        What if the population of the bar is as wealthy as Gates? My point is that you can't find 90000 people who are as wealthy as Gates. In fact, you can't find 90000 people whose average wealth comes anywhere close to Gates -- even the Forbes 400 average out at a paltry $6.7B, and you'd need to stock the bar with 83300 people with that level of wealth before Gates would fail to raise the average wealth by $1M. I think the average wealth among the top 90000 people is around $100M, so you'd need to have around 89900 of them... plus or minus a few thousand depending on how the stock market is doing on any particular day.

Reminds me of a similar factoid: Wayne and Brent Gretzky hold the National Hockey League record for most combined points by two brothers: Wayne Gretzky with 2,857, Brent Gretzky with 4.
- antognini 9y ago
  I heard it told a little less charitably: Who were the most successful NHL brothers? Wayne Gretzky and whoever Wayne Gretzky's brother was. I've also heard a nerdier variant: Who was the most influential father-son pair in mathematics? Gauss and whoever Gauss's father was.

It turns out, though, that the median family of four has an income pretty close to the average family of four, so this point is a little less clever than most of the folks who are making it believe. http://www.washingtonexaminer.com/actually-the-average-family-of-four-really-will-save-more-than-2000-from-this-bill/article/2644184 http://www.washingtonexaminer.com/actually-the-average-famil...

By the way you may be surprised to know that the average person as slightly more than one ovary and slightly less than 1 testicle. It's true!
