    probability of finding 2 random DNA fragments matching between genomes

    Hi all, I have a question about probabilty. There are 2 genomes (a long string, composed of 4 letters: A, T, G & C), each 150,000 bases (letters) long. Now, I generate 10,000 random fragments (sub-strings) from each genome, each exactly 20 bases long. What is the probability of finding...
