Answer
$ P = 7.9 \%$
Work Step by Step
To calculate the percentage time the system spends in the central
configuration for N = 200, we need to use the following equation
$ P = \frac{W}{N_{total}} \times 100$
Subtitute values in (d) and (e)
$ P = \frac{1.00 \times 10^{29}}{1.268 \times 10^{30}} \times 100$
$ P = 7.9 \%$
