Rather than insisting that all the molecules be in the left half of a container, suppose we only require that they be in the leftmost 99% (leaving the remaining 1% completely empty). What is the probability of finding such an arrangement if there are 100 molecules in the container? What if there are 10,000 molecules? What if there are 1023?

# Step 1

We will first find the probability of one particle in this particular 1% region. Then we will find the probability of finding another particle in the same region and similarly we will extend the solution to 100 particle.
