sequential experiments: probability

This probelm concerns random number generation.  The gist of the probelm is that 10 numbers are selected from the interval [0,1], and goal is to discover the probabilty that the first five numbers are less than 1/4 and the last five numbers are greater than 1/2.

I'm stuck on what to do this kind of problem.  I know how to find the probability of a number greater thanx or less than x, but I'm lost with how to work with a problem that involves the sequence.
