The flour beetle, Tribolium castaneum, has 1010 chromosomes, roughly equal in size, and it also has eight Hox genes (Brown et al. 2002). If the eight Hox genes were randomly distributed throughout the genome of the beetle, what is the probability that all eight would land on the same chromosome? Give your answer in scientific notation. Give the significance to two decimal places.
