Error in chap03ex.ipynb #63

Closed ghost closed 7 years ago

ghost commented 7 years ago

Hi, I noticed that in 7th cell when we are plotting the pmf, pmf instance should be updated in 6th cell. Not the hist instance. 

n = hist.Total()
pmf = hist.Copy()
for x, freq in hist.Items():
    pmf[x] = freq / n

Good catch! That should be fixed now. Thanks!
