Answer:
1 out of 7 (1/7)
Step-by-step explanation:
Do some research. Studies show that an entire 1 billion people smoke. There are about 7 billion people i the world, right? so, the answer of picking a non-smoker is 6/7, and picking a smoker is 1/7. The average (or the probability of them both being smokers) is about 1/ 14 (I think, I hope, I pray)
Hope this helps!
