Why does the Coriolis Effect Happen?
Well, as you move north or south on/above the Earth's surface, your tangential rotational velocity becomes different than that of the ground below you, since rotational velocity is greater at the equator. As such, you'll start moving relative to the ground in a direction determined by whether you sped up or slowed down relative to the surface.

This is permutation with repeated symbols. Simply take the answer for 11 unique letters, 11!, and divide it by the number of possible arrangements of the repeated letters, i's s's and pp's, within each ordering. So you get (11!)/(2!4!4!).
