Screwdrivers and the 50-50-90 rule

For those of you unacquainted with the 50-50-90 rule it states as follows:

If there is a 50% chance of a good outcome and a 50% chance of a bad outcome 90% of the time you will experience a bad outcome.

To the screwdriver.

When Al was on board he was up on the top of the mast and dropped a screwdriver. It of course went ping, pang, plunk, splash. We joked that he owed me $2.00 for a new screwdriver (I am holding you to it, Al.) In the store the other day I went to purchase the replacement screwdriver. Compared to the cost of the single replacement screwdriver I was able to purchase a set of seven screwdrivers for only a few bucks more even though six of them duplicated screwdrivers in my toolbox. So I did.

This morning I replaced the broken bracket for the hailing horn. I dropped the screwdriver. Ping, pang, plunk, splash. Need I tell you which of the new seven screwdrivers I dropped overboard?

Fair winds and following seas :)
