Answered by: Mark Haynes on: Feb 13th, 2012
I hit the send before I was finished, to continue: since the random picking of a number under 20 is still a independent event, the chance for picking a 2nd prime number is still the same... 40%
Answered by: Mark Haynes on: Feb 13th, 2012
Given that there are 8 Prime Numbers under 20, and if the limit is only random numbers under 20 then there is a 40% chance of getting a prime number.
