I have built an urn model for a DNA sequence. I have taken the letters from a sequence 1946 nucleotides long. The urn contains 259 Adenines, 699 Cytosines, 401 Thymines and 587 Guanines How many start codons will I find on average in the entire sequence when I draw all of the bases from the urn without replacement? Please I'm not too sure how to tackle this.

Which open reading frame is likely to represent a protein- coding sequence, and why? Which are probably not functioning protein-coding sequences, and why?
