### A FUN math problem from L!

I am studying for the SAT right now and in my practice book, there is an INSANELY HARD(at least for me) problem that I CANNOT figure out. My book overs no explanation on it as it is in one of the practice tests, just the answer. I thought I'd post it here to see if anyone knew how to figure it out. It's probably not as hard as I think it is, but it's just been bugging me so much and as it is summer, there is no teacher in sight to ask for help.

Here we go:

On the disk shown above, a player spins the arrow twice. The fraction *a/b* is formed, where *a* is the number of the sector where the arrow stops after the first spin and *b *is the number of the sector where the arrow stops after the second spin. on every spin, each of the numbered sectors has an equal probability of being the sector on which the arrow stops. What is the probability that the fraction *a/b* is greater than 1?

(A) 15/36

(B) 16/36

(C) 18/36

(D) 20/36

(E) 21/36

(the sections are supposed to all be equal by the way...)

and the book says that the answer is A. If anyone knows how to do this and wishes to enlighten me, I would greatly appreciate it!

### Music Monday!!

This feels very summery to me. I am about to start learning some new Telemann pieces for the summer in my cello lessons, which is why I decided to post this piece in particular!
