Take 1,000,000 samples from the normal distribution using the np.random.normal() function. The mean mu and standard deviation sigma are already loaded into the namespace of your IPython instance.
Compute the fraction of samples that have a time less than or equal to Secretariat's time of 144 seconds.
Print the result.
