Wrong Co in Antithetic Variate Notebook

[AlvaroMaza]

Hello,

First of all, thanks for uploading these notebooks, your videos are super useful!

I was going through the Monte Carlo Variance Reduction with Antithetic Variates one, and I have noticed that there is a small misspelling in a print:

When you compare it with the solution without the Antithetic Variance, you should print:

print("Call value is ${0} with SE +/- {1}".format(np.round(C0w,2),np.round(SE,2)))

instead of

print("Call value is ${0} with SE +/- {1}".format(np.round(C0,2),np.round(SE,2)))

I know it is a very small issue, but it makes the plot not match the number printed, and I was finding it confusing until I found this
