The rate of 75 mutations per generation was genome-wide, or over roughly 3 billion base pairs. The subsequence of the genome for the constituents of hemoglobin are roughly 3,000 base pairs long.

a) How many mutations would we expect in this important protein in one generation?

b) Find the probability of exactly zero mutation in this small part of the genome.

c) Find the probability of exactly 1 mutation in this small part of the genome
