It is often cited that there are half as many divorces as marriages in the US, so one concludes that average marriages have a 50% chance of ending by divorce. While I was a graduate student, among my peers there were twice as many divorces as marriages, leading us to conclude that average marriages would […]

## Worries while flying

Two statisticians were travelling in an airplane from LA to New York. About an hour into the flight, the pilot announced that they had lost an engine, but don’t worry, there are three left. However, instead of 5 hours it would take 7 hours to get to New York. A little later, he announced that […]

## Reducing travel risk

## Answering machine

Hello, this is probably 438-9012, yes, the house of the famous statistician. I’m probably not at home, or not wanting to answer the phone, most probably the latter, according to my latest calculations. Supposing that the universe doesn’t end in the next 30 seconds, the odds of which I’m still trying to calculate, you can […]

An engineer, a physicist, and a mathematician are trying to set up a fenced-in area for some sheep, but they have a limited amount of building material. The engineer gets up first and makes a square fence with the material, reasoning that it’s a pretty good working solution. “No no,” says the physicist, “there’s a […]

## Refrigerate elephants

Analysis: 1. Differentiate it and put into the refrig. Then integrate it in the refrig. 2. Redefine the measure on the referigerator (or the elephant). 3. Apply the Banach-Tarsky theorem. Number theory: 1. First factorize, second multiply. 2. Use induction. You can always squeeze a bit more in. Algebra: 1. Step 1. Show that the […]
