ugh, yes it works, no, not what I had in mind nor what you'll need for the next step. one more perfectly good "wrong" answer and it's clue time I think.
No, and by the looks of that excellent answer, I may not have made it any more specific with my typo correction. But hopefully it will be easier (I dare say).
OK, then what about question 2? Cant visualize the ratios you mentioned in this case. But logically one would think the probability of 1. and 2. would be (or would approach being) the same. Am probably missing something. Will have to keep thinking on this. And when I say "have to" it's because my mind will not give me a choice! Think my boss will understand?
wooden hill.
You and plasmid have indeed knocked out the first one. Only 2. and 3. remain and regretably inform you that your guesses above are not them.
