A Draw
There are 16 people including me and my friend John left in a hat. A draw is going to take place.

What is the probability of me being drawn against John?

$\frac{1}{15}$

Consider you being the first of the 16 people, so there is a chance of 1 that you will be picked.

Therefore there are now 15 people left, any one of which could be John
