Ten identical crates each have dimensions [unparseable or potentially dangerous latex formula] ft x [unparseable or potentially dangerous latex formula] ft x [unparseable or potentially dangerous latex formula] ft. The first crate is placed flat on the floor. Each of the remaining nine crates is placed, in turn, flat on top of the previous crate, and the orientation of each crate is chosen at random. Let [unparseable or potentially dangerous latex formula] be the probability that the stack of crates is exactly [unparseable or potentially dangerous latex formula] ft tall, where [unparseable or potentially dangerous latex formula] and [unparseable or potentially dangerous latex formula] are relatively prime positive integers. Find [unparseable or potentially dangerous latex formula].
