17 (number)
17 (seventeen) is the natural number following 16 and preceding 18. It is a prime number.
17 was described at MIT as"the least random number", according to the Jargon File.[1] This is supposedly because, in a study where respondents were asked to choose a random number from 1 to 20, 17 was the most common choice. This study has been repeated a number of times.[2]
