Imagine a hollow cube. A ant is placed in a corner and a spider in the opposite corner.  Both start to move along cube edges and when they each reach a corner, they can move in any direction (x,y,z) with probability 1/3.  Both also move from corner to corner at the same pace.  To the nearest percent, what is the probability that after 10 times of changing corners, the spider has ran into the ant?

Well, Happy New Year 2014!  Speaking of which, how many zeroes are there at the end of "2014!" ?

This is 2014 factorial.  In other words, "1 * 2 * 3 * 4 * ... * 2013 * 2014"
