What are the chances of a horse matching or beating Secretariat's record?
Assume that the Belmont winners' times are Normally distributed (with the 1970 and 1973 years removed), what is the probability that the winner of a given Belmont Stakes will run it as fast or faster than Secretariat?

Anleitung zur Übung
- Take 1,000,000 samples from the normal distribution using the
rng.normal()function. The meanmuand standard deviationsigmaare 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.
