 (or as someone above posted, it's literally just 1-(199/200)^16 )

### REPLY:
Man I don't understand statistics. What's wrong with my logic here: You have a 1/200 chance of getting Apple stock every time you refer a friend. He referred 16 friends. Each time you draw, you have a 1/200 chance of winning. 16*(1/200)= 8% chance of getting Apple stock at least once.
