Step 2 in the Alias Algorithm should read

  2. If Z < Q(Y) return X = Y, else return X = A(Y).

The second to the last line of code should read j=16 instead of i=16

Since the number of TH outcomes is 3, the first line of the
displayed equation should have (3 - 0.25x20) instead of (4 - 0.25x20).
This causes several other changes: V should be 7.6 instead of 7, in
the 4th line from the top the probability should be 0.938 instead of
0.906. In the 5th line the complement probability will be 0.062
instead of 0.094 and in the 6th line the probability as a percent
is 6.2 instead of 9.4. 

The meaning of the table is that, given the coin is fair, the statistic V will
be 7.815 or less with 95% chance. By interpolation, the table value for p = 0.90
is 6.89. This means that 10% of the time, a fair coin will give V a value
exceeding 6.89. Thus, if we say our coin is not fair on the basis of this
experiment, there is a 10% chance we are wrong.
