Imagine that a long stretch of single-stranded dna has 24% adenine, 18% thiamine, 30% cytosine, and 28% guanine. (these make up the nucleotides of the dna.) suppose that you randomly sample four nucleotides. a. what is the probability of randomly drawing 3 adenines and 1 nucleotide that is not thiamine? b. what is the probability that all four are cytosine or guanine? for instance, the sequence ccgg would qualify since it made up of only c’s and g’s. c. what is the probability that you draw either three or exactly four cytosines in four random samples?
