I was playing with Wolfram|Alpha, and I typed in my ten-digit phone number. And it was prime! I have a prime cell phone number! Of course, I tried this with other numbers... my SSN isn't prime, and neither is my dad's phone number. My seven-digit phone number can be divided by two square numbers... so it's really not prime... But I still find the prime phone number interesting. Question 1: Do any of you have prime phone numbers? (You don't have to say what the number is) Question 2: Does anyone know the probability of a ten-digit phone number being prime?
