Solutions don't match in Covariance module 1.2.1

[JCarlosBarradasR]

In the first exercise of module 1.2.1 is asking for a uniform distribution but the solution contains a normal distribution, which also should say: 'distribution = stats.norm(0, 1)', as 'distribution = stats.normal(0, 1)' generates an error.
In the second set of exercises asks for correlations, but the subject is about covariance. The referenced solution file "solutions/correlations.py" does not contain the solutions for this exercise.
