(We assume that cells never divide before time t=10 min.) (a) find the mean time for division In pdfs, the area of the probability is equal to one. The mean is equal to the After integrating by parts I get the mean time being 11. This is however not the right answer. I found R to be 1, as it is the normalization constant found by finding the area of and solving for R.
