So if we carry out the Edmund degradation process on this entire polypeptide, what is the probability that we're going to obtain a correct sequence of amino acids? Well, to calculate this probability we simply have to multiply the individual probabilities of each one of those processes. So we have zero 97 for the first process, zero 97 for the second process, zero 97 for the third process and so forth all the way to the 50th process when we basically release this final amino acid. And so we have zero point 97 to the 50th power and that gives us about zero point 22 and that is equivalent to a 22% likelihood. So that's a relatively small likelihood. So what that means is there is a 78% chance that our sequence will not be the correct sequence of amino acids.
